Introduction

At its core, unified communications (UC) solutions involve software (such as Microsoft® Lync) that runs on servers connected to a local area network (LAN) and hardware such as media gateways that provide access to the public switched telephone network (PSTN) and IP phones. In an enterprise deployment, the servers will typically be at a data center location and users will be spread out amongst multiple geographically dispersed campuses and branch office locations with their own LANs connected to a wide area network (WAN) for intra-enterprise communications. Within the enterprise, quality of experience (QoE) for users at different locations is what makes the difference between employees embracing change and using the UC tools to enhance customer satisfaction and improve productivity or not. Within the network, the largest factor that impacts QoE is quality of service (QoS), which traditionally has challenges that make the implementation and management of QoS difficult. As enterprises consider UC solutions with Microsoft Lync, they will need to consider the holistic system including servers, storage, networking, management, planning, and services. HP has a complete portfolio to help enterprises deploy Microsoft Lync, including networking for data center, campus, and branch office locations. The HP FlexNetwork unified communications reference architecture (UCRA) provides the framework to discuss holistic networking for Microsoft Lync deployments. This architecture guide describes the HP FlexNetwork UCRA with Microsoft Lync; providing value proposition, requirements, best practices, reference design models, architecture components, and reference designs for Microsoft Lync deployments using HP Networking products and solutions. The intended audience for this guide is HP Networking solution architects, HP Networking technical consultants, and HP Networking partner pre-sales technical staff. Value proposition

Key drivers for unified communications with Microsoft Lync Microsoft Lync is an enterprise-ready unified communications platform. With Lync, workers can keep track of their contact’s availability; send an IM; start or join an audio, video, or Web conference; or make a phone call—all through a consistent and familiar interface accessible from almost any device. A user may wish to use: desktop, mobile device, or more traditional desk phone type end points. In addition, Lync is designed to fully integrate with the Microsoft Office products you use every day, including Outlook, Word, PowerPoint, and Excel. Microsoft Lync is designed to:

• Increase the business value of communications – Readily determine or locate immediately available expertise – Engage expertise with preferred or multiple forms of communication – Escalate to a voice or multiparty voice and video conference, share desktop, and collaborate in real time – Increase the speed of business by removing traditional messaging delays, inherit to single mode communications options that are traditionally standalone or “siloed” legacy communications systems (separate systems for telephony, video, email, etc.) – Enable migration strategies embracing interoperability with legacy systems for smooth, cost-effective shift for customers • Reduce costs through converged communications – Reduce travel via audio, video, and Web conferencing – Reduce PSTN calling charges via VoIP – Leverage additional cost savings through IP networks for one-to-one voice and multiparty conference calls – Reduce audio conferencing service charges – Retire separate PBX systems (some or all) – Provide shared workplace, home, and mobile communications support • Integration with the most popular productivity tools preferred by enterprises of all sizes – Integration with Microsoft Office, Exchange, SharePoint, Excel, and Outlook – Use instant messaging and presence in Office and SharePoint – Click to communicate with seamless escalation – Hold ad-hoc audio, video, and Web conferencing (interorganizational)

The networking equipment topology and solution selection guidelines for this reference architecture are based on the HP Networking FlexFabric, HP FlexCampus, and HP FlexBranch Reference Architectures. In addition to a network, a Microsoft Lync deployment requires servers and storage. The HP sizer for Microsoft Lync can be used to begin the planning process of determining how many and what kind of servers and storage devices will be required. In addition, the HP Lync 2500 User reference architecture guide provides details on a specific solution as an example.

HP FlexNetwork Architecture The HP FlexNetwork Architecture is a blueprint that enables enterprises to align their networks with their business needs by segmenting their networks. The HP FlexNetwork Architecture is designed to allow IT to manage these different network segments through a single pane-of-glass management application. Because the HP FlexNetwork Architecture is based on open standards, customers have the freedom to choose proven solutions for their businesses. Enterprises can segment their networks into the four interrelated modular building blocks of the HP FlexNetwork architecture as shown in figure 2: HP FlexManagement, HP FlexFabric, HP FlexCampus, and HP FlexBranch.

Open Scalable Secure Agile Consistent

The HP FlexNetwork Architecture:

• An open and standards-based solution—It mitigates the risk and cost of change when the network needs to adapt to new business requirements. It uses open networks to make it simpler for enterprises to move their applications to public and private cloud services. • Scales on three dimensions (functionality, connectivity, and capacity)—The network scales from basic functionality to feature rich, from limited connectivity to multisite large-scale connectivity, and from megabit to terabit capacity. • Secure—The architecture gives customers a consistent approach to securing all segments of the network like the data center, campus, and branch. In the data center, the architecture addresses the security needs of both physical and virtual compute platforms as well as public and private clouds. • Delivers agility—The use of standard protocols enable business agility, as IT staff can easily and efficiently make changes in existing networks as business needs change. • Delivers a consistent operating experience—Single pane-of-glass management application eliminates use of an array of different tools to manage the entire network including the data center, campus, and the branch for a common operating environment.

Dynamically optimize the network for UC with Lync with SDN SDN provides a programmable network that businesses can align to their business applications, automatically provision the network, and eliminate dozens or even thousands of working hours compared to how networking is done in the traditional way and without SDN. A recent innovation from HPN is the HP Virtual Services Router (VSR) combining SDN with Network Function Virtualization (NFV). In accordance with our vision, these products span the entire network from the data center to the campus and the branch. So a consistent SDN implementation goes from where the applications are generated in the data center to where they are demanded by users in the campus and the branch. HP VSR SDN Controller supports multiple applications and have opened up the API, training tools, and assistance to the broader ecosystem. Now, our alliance partners and independent software vendors can reignite the innovation across their IT strategy, delivering more services in less budget. These new applications will be easily accessible to all customers through the HP SDN App Store. These will be HP applications, jointly developed applications, partner-developed and certified applications, and ones from members of the community of users who wish to build their own standards-based SDN applications. HP is the only vendor pursuing an SDN strategy, which spans from user-to-data center and the entire network technology stack. Our partners, customers, and developers can leverage the open standards path to complete the customer solution. Deep integration, open standards, and supported technology—all to make the network become “invisible” to users providing faster, higher quality, more reliable, and applications-focused services to drive productivity and simplicity.

Requirements

Requirements for unified communications networking with Microsoft Lync include:

• End-to-end QoS • SDN dynamic programmability of QoS policies on a per-session basis • Networking at data center, campus, and branch office locations – Power over Ethernet chassis (PoE)/PoE+ for intelligent power for clients – Plug-n-play Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) autoconfiguration – High availability with sub-50 msec – 40GbE with 100GbE ready for video • Unified wired and wireless access across campus and branch office locations • Security – ACL style QoS for advanced granular policies – Layered security (IPS, virus throttling, and RF security) • PSTN access and local analog device connectivity • Remote site survivability solutions • IP Phones for Microsoft Lync • Single pane-of-glass network management with Microsoft Lync QoS reporting QoS requirements Requirements for QoS in the network include:

• How to measure QoS—metrics – Delay, latency • General requirement is to keep combined total 2 way delay/latency below 150 msec – Packet loss • Requirement for traditional VoIP is to limit packet loss to <1% loss end to end • Requirement for Microsoft RTAudio is to limit packet loss to <10% loss end to end – Jitter • General requirement is to limit jitter to <30 msec • Codecs and bandwidth – The Microsoft Lync 2013 Technet website for Network bandwidth requirements for media traffic explains the typical bandwidth usage that can be used for traffic engineering designs for different codecs • Video bandwidth usage

7 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

– Using H.264 codec at 320x180 resolution, maximum video payload bitrate is 250 Kbps – Using H.264 codec at 1920x288 resolution, maximum video payload bitrate is 2000 Kbps • Application sharing bandwidth consumption is dependent on session content and screen resolution – These are TCP-based sessions with built-in congestion control with bursty traffic by nature • Call Admission Control (CAC) – CAC is implemented by the policy server role in Microsoft Lync Server – Administrators configure logical sites based on groupings of subnets – WAN link bandwidth policies – Applied dynamically when session crosses network link with policy set – Seamless support for roaming users moving between different sites – PSTN reroute – Allows Internet to be used for overflow of traffic – Supports alternate path and failover of video sessions • Network – Differentiated services code point (DSCP)—DiffServ – The challenge is that DSCP tagging is traditionally not done by Lync

Challenges of voice networking deployments with Lync:

• Microsoft Lync can deliver a highly effective primary voice environment without desk phones, but controlling QoS on the network is a challenge when not tied to a hard phone on a specific voice VLAN. – Sprint case study—Only 20% of users have IP desk phones • Network engineers don’t want to trust DSCP/QoS on PC endpoints at the edge switch. This would enable anyone to access high-priority network tiers for file sharing, Web traffic, etc. • Network engineers don’t want to re-mark specific network traffic at the edge for Lync media TCP/UDP ports. – Cumbersome, easy to exploit, and hard to change later. – Challenge in IT politics. Active directory, Lync admins, and network team must collaborate completely. • Server engineers will set Lync client port ranges and active directory enforced QoS policies if high quality voice over wireless is desired. These changes are required to enable QoS for Lync on wireless networks, requirement of wireless multimedia (WMM). Best practices

From a Microsoft Lync perspective, as described on their Technet website for Microsoft Lync 2013 à Planning à Network planning à Managing quality of service (QoS), these are the items that should be performed to ensure increased user quality of experience measurements:

• Enabling QoS for devices that are not based on Windows® • Configuring port ranges for conferencing, application, and mediation servers • Configuring port ranges for edge servers • Configuring port ranges for Microsoft Lync clients • Configuring QoS policies for conferencing, application, and mediation servers • Configuring QoS policies for A/V edge servers • Configuring QoS on Microsoft Lync phone edition clients

In order for voice and data traffic to behave correctly on a shared network, there are a few best practices that should be followed:

• Voice and data traffic should be separated—The use of a voice VLAN allows the voice traffic to be prioritized higher than the data traffic throughout the network topology. • QoS policies should be enforced—All switches and routers within the environment should participate in the QoS infrastructure allowing the voice and data traffic to be controlled throughout the network topology. • Configure WAN links for voice traffic—Ensure that there is sufficient bandwidth provisioned on the WAN links and establish an appropriate service level agreement with the service provider.

8 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

• Use open standards—Relying on nonproprietary features to configure the voice environment provides future proofing of the QoS infrastructure.

Voice VLANs Virtual LANs (VLANs) are used to segment the network and provide security by dividing up a branch office network into multiple logical groups. By implementing VLANs, enterprises can provide better granularity in defining routing, QoS, and security policies for different groups of network clients. When voice and video communications are implemented on a branch office network, a voice VLAN is created and configured on switch or router Ethernet ports to keep this traffic separated from the data traffic. With HP Comware devices, a port can be assigned to a voice VLAN automatically or manually. The automatic mode is typically used in scenarios where PCs and IP phones are connected in series, they access the network through the device, and ports on the device transmit both voice and data traffic simultaneously. The manual mode is suitable for scenarios where only IP phones access the network through the device, and ports on the device only transmit voice traffic. In addition, a voice VLAN port can operate in either normal mode or security mode, which determines if a voice or data packet is forwarded across the VLAN. Due to the sizing of branch offices in the HP FlexBranch Reference Architecture, one voice VLAN is typically sufficient for each branch office.

Voice QoS A Voice over IP (VoIP)-capable network is concerned about both layers of QoS—layer 2 and layer 3. At layer 2, the Ethernet priority of the packet is represented by the 802.1p bits. These three bits reside in the 802.1Q VLAN header and contain the values of 0 through 7. These values are mapped into the physical queues depending on the policies set on the switch. Generally, the 802.1p values determine how the traffic will be serviced in the queues. For example in a strict QoS implementation, the high-priority traffic will be serviced before the lower priority traffic. At layer 3, the IP priority of the packet is represented by the DSCP. This code point is defined by 6 bits in the IP header of the packet. These bits allow the priority of the packet to be maintained across layer 3 or routed boundaries. Many vendors use the DSCP value of 46 (101110) to represent the VoIP traffic. This value is usually mapped by most network vendors to the Expedited Forwarding (EF) queue. On HP Networking switches, a DSCP value of 46 is mapped to priority 7. For the VoIP traffic to be properly handled within a network topology, the QoS policies must be configured end to end— layer 2 or priority bits for the switches and layer 3 or DSCP bits for the routers. Without a consistent QoS policy, the voice quality degrades in the presence of bursty data traffic.

Voice DHCP When a voice device such as an IP phone is connected to the network, it needs an IP address. The IP address can be manually configured using the phone’s user interface or automatically configured using DHCP. When DHCP is used, the DHCP server used for the branch office network puts the IP phone in the voice LAN and configures other network parameters such as NTP Server, default gateway, and voice VLAN of the IP phone. In some cases, a network component such as the router or core switch may be used to provide local DHCP services at the branch office. If the DHCP server is on a different network segment from the branch office, the ProVision switches must be configured to use an IP helper address to support forwarding IP address requests to the DHCP Server.

LLDP-MED Over and above basic data, VoIP has well-defined needs:

• Plug-and-play provisioning • Simplified management and accurate network topology • Precise device move tracking for emergency call service • Rapid identification and troubleshooting of call quality issues • VoIP specific inventory management • Vendor-independence, allowing different IP telephony systems to interoperate on one network • Need an open standard discovery protocol

IEEE-802.1AB-2005 LLDP is complete and seeing widespread adoption:

• LLDP provides the base capabilities, but is not sufficient for IP telephony and real-time video

9 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

• Published as ANSI/TIA-1057 (April 2006) • HP Networking was first in the industry to support LLDP-MED

LLDP-MED provides:

• Interoperability – Provide vendor-independent management capabilities, enabling different convergence endpoints to interoperate on one network • Automatic deployment of convergence network policies – Voice VLAN, layer 2, and DSCP QoS policies • Location services, including ECS – Enablement of E-911, 999, 112 for IP telephony through physical location • Detailed inventory management capabilities – Location information and accurate topology is made available – Switch acts as proxy to collect inventory—as few endpoints support SNMP • Advanced PoE – Fine grain power management to support more phones per switch – Backup power conservation to extend UPS battery life during disasters • IP telephony network troubleshooting – Detect incorrect voice VLAN, QoS, and duplex mismatch • Frequent cause of voice and video quality issues but very hard to diagnose

LLDP-MED key points include:

• LLDP runs after 802.1X authentication – Improved security, since unauthorized devices cannot learn the switch IP address, or gain access to voice network by spoofing discovery frames, like with Cisco Discovery Protocol (CDP) • 802.1D compliant switches, never forward LLDP frames – Proprietary L2 protocols, like CDP may leak across other vendor switches or if the protocol is disabled, resulting in less reliable physical topology • LLDP-MED provides “fast start” behavior – Rapid startup and location discovery is very important for IP telephony – At startup, endpoints will initially advertise at a faster rate for a limited time • Easy to use with minimal configuration required – Assign a “voice” VLAN to ports – Assign the wall jack location to ports (for physical location, like E-911)

Reference design models

A reference design model describes the general architecture and framework of a solution. Reference design models describe categories of products and are intended to be product-agnostic. Midmarket The HP FlexNetwork UC Lync midmarket reference design model supports 250–2,500 users in a Microsoft Lync environment. For a network topology for this size, the HP FlexCampus Reference Architecture is used to design the core switching, core routing, and unified wired and wireless infrastructure. Elements of the HP FlexBranch Reference Architecture (FBRA) including the Session Initiation Protocol (SIP) enhanced media gateway functionality are also included. For the midmarket UC Lync solution, an HP FlexCampus 2-tier network design is used with 1 or 2 core switches (2 for redundancy) and a set of access switches that connect into the core switches. The access switches provide PoE or PoE+ as needed and support switch aggregation. The servers that host Microsoft Lync are connected to the core switches. A core router is used to provide connectivity to the WAN and Internet. A firewall exists between the core switching and core routing elements to provide secure access for IP traffic in both directions. Mobility controllers and wireless access points (APs) make up the rest of the unified wired and wireless solution.

10 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

A SIP enhanced media gateway is connected to the core switch, providing PSTN access and connectivity to local analog devices. The SIP enhanced media gateway communicates using the SIP protocol to the Microsoft Lync mediation server component. PSTN interfaces such as E1, T1, ISDN BRI, and FXO are installed in the SIP enhanced media gateway in a modular and scalable fashion. Local analog devices such as analog phones, fax machines, and modems are connected using modular and scalable FXS interfaces on the SIP enhanced media gateway. SDN is enabled with this reference design model using the HP Virtual Application Network (VAN) SDN controller, Lync SDN API, HP Network Optimizer SDN application, and OpenFlow-enabled switches. HP Intelligent Management Center (HP IMC) is used to provide holistic network management capabilities along with monitoring of Microsoft Lync topology, alarms, and Lync QoS measurements. The midmarket deployment model is shown in the following figure. Figure 5. HP FlexNetwork UCRA with Lync midmarket reference design model

Enterprise The HP FlexNetwork UC Lync enterprise reference design model supports 2,500+ users in a Microsoft Lync environment. In this environment, the primary Microsoft infrastructure is hosted in a data center and secondary (redundant) Microsoft infrastructure is distributed across certain campus locations. For a network topology of this size, the entire HP FlexNetwork Reference Architecture is used, including HP FlexFabric, HP FlexCampus, and HP FlexBranch. The servers hosting the primary Microsoft Lync infrastructure are located at a data center where an HP FlexFabric 2-tier reference design model with core routing is used to provide high-speed, low-latency, modular, and scalable connectivity at the data center. An HP FlexCampus 2-tier reference design model is used with 1 or 2 core switches (2 for redundancy) and a set of access switches that connect into the core switches. The access switches support LLDP, PoE, PoE+, and support switch aggregation. The servers that host secondary (redundant) Microsoft Lync infrastructure are connected to the campus core switches. A campus core router is used to provide connectivity to the WAN and Internet. The switching and routing infrastructure at the data center and all campus locations in an enterprise reference design model are intended to be redundant by default. In smaller campus locations, a high-end branch router from the HP FBRA maybe better suited for the performance requirements, while also providing converged infrastructure by integrated routing with voice. A SIP enhanced media gateway is connected to the core switches in the data center and campus locations, providing PSTN access and connectivity to local analog devices. The SIP enhanced media gateway communicates using the SIP protocol to a Microsoft Lync mediation server component. PSTN interfaces such as E1, T1, ISDN, BRI, and FXO are installed in the SIP enhanced media gateway in a modular and scalable fashion. Local analog devices such as analog phones, fax machines, and modems are connected using modular and scalable FXS interfaces on the SIP enhanced media gateway. The PSTN gateway

11 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

at the data center can be used for centralized calling, while the PSTN gateways at each campus can be used for local PSTN access and enterprise-wide least cost routing of calls. Remote site survivability is included in this reference design model for the campus locations that do not have the secondary (redundant) Microsoft Lync infrastructure. The HP FlexNetwork UCRA Lync enterprise reference design model is depicted in figure 6. Figure 6. HP FlexNetwork UCRA with Lync enterprise reference design model

Each branch office can have different scalability, resiliency, and voice requirements. For example, some smaller locations may be all-IP and therefore not require local analog device or PSTN connectivity. In these reference design models, branch offices are based on HP FlexBranch reference design models including standalone router or switch, 1-tier for small and large footprints, and 2-tier. Branch office types in these reference design models include:

• All-IP for standalone router and small 1-tier • Standalone router • Standalone switch • 1-tier for small, medium, and large sizes • 2-tier

At each branch office that requires local analog device or PSTN connectivity, a SIP enhanced media gateway is connected to the branch office switch. The SIP enhanced media gateway communicates using the SIP protocol to a Microsoft Lync mediation server component. PSTN interfaces such as E1, T1, ISDN BRI, and FXO are installed in the SIP enhanced media gateway in a modular and scalable fashion. Local analog devices such as analog phones, fax machines, and modems are connected using modular and scalable FXS interfaces on the SIP enhanced media gateway. Remote site survivability is included in this reference design model for branch office locations that support a larger number of users.

SDN The HP FlexNetwork UCRA with Lync SDN reference design model provides support for deployment of the HP Network Optimizer SDN application for Microsoft Lync. In this environment, the HP VAN SDN Controller is used with the HP Network Optimizer SDN application along with the Microsoft Lync SDN API to dynamically program QoS parameters using the OpenFlow protocol that enhances the overall quality of experience for the user. On top of an existing Microsoft Lync environment, a Microsoft Lync Dialogue Listener (LDL) application is installed that runs the Microsoft Lync SDN API. The LDL is configured to communicate with the HP Network Optimizer, which as an SDN application, communicates with the HP VAN SDN Controller to send device configuration to devices in the path of a Microsoft Lync session that needs dynamic QoS configurations. The primary components of this reference design model include:

• Existing Microsoft Lync environment

Architecture components

This section describes guidelines used in selecting the individual components of the HP FlexNetwork UCRA with Lync. HP FlexFabric Reference Architecture The HP FlexFabric Architecture extends the HP Converged Infrastructure to the data center and provides the following benefits:

• Combines advanced, standards-based platforms and advanced networking technologies to optimize performance and latency in virtualized server environments • Converges and secures data center network, compute, and storage in the physical and virtual worlds • Reduces complexity • Enables rapid businesses-aligned network provisioning • Lowers TOC • Consolidates multiple protocols into a single fabric that can easily flex with changing workloads

Optimized 2-tier model The HP FlexFabric reference architecture describes multiple solutions that fit a broad range of customer requirements for data center networking. The one selected for the HP FlexNetwork UCRA with Lync is the optimized 2-tier reference design model. Typical 2-tier top of rack (ToR) deployments will utilize 2 to 4 core switches utilizing IRF, which then in turn connect to various ToR switches. These ToR switches, which may or may not be utilizing IRF, will then connect to servers within the same rack.

• Layer 2, 2-tier ToR designs extend VLANs across the entire data center and are optimized for virtualized environments where VMs maybe moving from rack to rack or data center to data center. • Layer 3, 2-tier ToR designs can isolate VLANs within each rack, and still provide for good scalability and expansion capabilities.

Following is an example of the HP FlexFabric optimized 2-tier reference design model.

HP FlexBranch UC with Lync reference design model In a unified communications deployment model, the branch office is part of a centralized unified communications and collaborative environment. IP phones at the branch get their service from a centralized IP-PBX or UC system via WAN connectivity. The IP phones get their IP address from a local or centralized DHCP server. The IP phones may also require authentication using 802.1x or LLDP-MED. The branch office may have analog devices such as analog phones or facsimile (fax) machines. A small branch office may have only a few analog lines to the central office for PSTN connectivity using FXO interfaces, or larger branch offices may have T1/E1 connectivity when they require more than a few lines to the PSTN. Typically, connections to the PSTN for large scale connectivity is done at the central site, leaving the requirement for one or more analog FXO lines to the central office for emergency calling or survivability use. The following diagram illustrates this deployment model.

HP FlexBranch reference architecture product selection guidelines The HP FBRA incorporates sizing as one of the primary methods to identify the right products for a particular set of customer requirements, but it also incorporates functionality. This is accomplished by first overlaying the size over a reference design model followed by considering the functional requirements. First, consider sizing guidelines:

• Map these sizing guidelines onto an HP FBRA reference design model • HP FBRA small branch offices are designed for 0–49 users • HP FBRA large branch offices are designed for 50–100+ users

Then, consider the functional requirements:

• There are two sets of recommendations for each size – Group 1 • Increased capacity, resiliency, and performance – Group 2

20 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

• Cost-effective or functional alternatives – There is nothing fixed about the products for each set of recommendations • Mix products as needed

Intuitively, a branch office can be classified by its sizing, which typically correlates closely to the physical infrastructure and deployment models that are associated with that sizing. For example, a small branch office typically requires less bandwidth and fewer switching ports than a larger branch does. However, just because a branch office is small, it does not mean it will have less stringent WAN, QoS, or security requirements. Also, as we consider mobility requirements, a small branch office could have carpeted floors or high ceilings; each of which would require different kinds of access points. A large branch office could have one of these—or both but would typically require a larger number of access points. The figure here illustrates the general guidelines for products in the HP FlexBranch reference architecture. Figure 17. HP FlexBranch product selection guidelines

Unified wired and wireless solutions The mobility layer provides access to the network for wireless devices, and can be implemented in an autonomous or controller-based WLAN architecture. In the autonomous architecture, full-featured APs provide wireless coverage for a specific area. These intelligent edge devices can enforce a company’s access policies, securing wireless communications through industry standard authentication and encryption methods. In addition, autonomous APs can apply sophisticated QoS measures and enable layer 2 roaming as long as the same Virtual Service Community (VSC) is supported in the APs. Regardless of architecture choice, multiple VSCs can provide wireless access for users. Each VSC defines settings for one WLAN. By creating multiple VSCs, different services can be supported for different wireless users. The HP Multi Service Mobility (MSM) solution consists of a selection of controllers and APs designed to meet the mobility and diverse application needs of various size customers. With the widespread adoption of 802.11, users have come to expect wireless LAN networks (WLAN) to be available anywhere from school, to home, to the office. Additionally, business grade wireless service requirements have grown beyond support for just data traffic; it is expected to support voice, video, desktop sharing, and other unified communication (UC) applications managed on platforms such as Microsoft Lync. The Microsoft Unified Communications Open Interoperability Program (UCOIP) includes a Wi-Fi network infrastructure qualification program to test and qualify that all technical specifications defined by Microsoft are met and the solution fully supports all required features for Microsoft Lync. The HP MSM solution is qualified for Microsoft Lync Server 2010 and 2013. The HP mobility product portfolio is illustrated in the next figure.

• Analog and digital SIP media gateway – Multiple interface types to connect to PSTN, legacy PBX’s, and local analog devices • Including FXO, FXS, ISDN BRI, E1 voice, and T1 voice – Modular and scalable configurations • Integrated SIP stack

An enterprise voice deployment includes enhanced SIP media gateways at data center, campus, and branch office locations in a Microsoft Lync environment.

24 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

A SIP media gateway is a device that provides voice connectivity from a branch office to the PSTN and analog voice devices located at the branch office. Deploying the SIP media gateway functionality on a modular router device helps enterprises by reducing the number of devices required for a branch deployment and to converge voice and network functionality. A SIP media gateway uses SIP to communicate with an IP-PBX or ITSP for signaling of voice calls and provides the voice path between voice devices and the physical interfaces to the PSTN/IP-PBX. SIP media gateways support the following voice connectivity:

• Foreign Exchange Office (FXO)—Analog voice lines that connect to a central office (CO) in the PSTN or to a legacy PBX • Foreign Exchange Subscriber (FXS) —Analog voice lines that connect to local analog devices such as analog phones, fax machines, modems, or overhead speaker systems • Electronic and Magnetic (E&M)—Voice lines that are used to connect to a CO or legacy PBX • E1, T1, ISDN BRI S/T modules—Digital voice lines that connect to a CO, service provider (SP), or legacy PBX • PSTN to analog phone/fax connectivity • Fax capabilities: – Fax from PSTN to analog fax or SIP/T.38 fax – Fax from analog fax or SIP/T.38 fax to PSTN – Fax between SIP/T.38 fax and analog fax

The HP MSR voice solution is provided by software and voice modules. The voice software functionality of the HP MSR Series is built-in the HP Comware software of the router. Voice modules are inserted into the router to provide physical voice connectivity, such as local analog devices to FXS ports, central office POTS lines to FXO ports, or PSTN digital trunks to T1/E1 voice ports. In its role as a SIP enhanced gateway, the HP MSR Series can be used in a Microsoft Lync 2010 or Microsoft Lync 2013 environment providing:

• Analog and digital SIP media gateway – Microsoft UCOIP certified to make/receive calls – Multiple interfaces types to connect to PSTN – Wide range of WAN, LAN, and voice interface options • Open and scalable – Based on open standards e.g., SIP – Interoperable with third-party UC solutions – Highly scalable routing and voice platform – TCP and TLS to make and receive calls

The HP MSR Router Series can be deployed in branch offices from small to large, in different sizes of campus locations and also at the central site. Each of these locations have different scalability and resiliency requirements that can be met with different HP MSR Router Series models. HP MSR voice SIC, MIM, or FIC modules are added to the HP MSR Router Series chassis to provide analog or digital voice connectivity to local analog devices, a local PBX/IP-PBX or to the PSTN. Microsoft UCOIP qualification indicates that the PSTN gateway can be deployed in Microsoft Lync systems. The HP MSR20/30/50 Series are qualified to be used as a SIP enhanced gateway in a Microsoft Lync 2013 environment, with the HP MSR Series providing:

• Integrated voice gateway – Microsoft UCOIP qualification to make and receive calls – Wide range of WAN, LAN, and voice interface options • Reliability and cost savings – Enables reliable real-time communications – Facilitates calls over the PSTN • Open and scalable – Based on open standards such as SIP – Highly scalable routing and voice platform – TCP and TLS to make and receive calls

25 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

– Interoperable with third-party UC solutions – Based on open standards and SIP

For details on the HP MSR Series qualification with the UCOIP, refer to the Microsoft Technet webpage. The following table describes the maximum capacity of the different HP MSR20/30/50 Router Series related to voice interfaces. The capacities are based on:

• Maximum available FXS, FXO, E1, and T1 modules • 30 voice channels per E1 port • 23 voice channels per T1 port

Remote site survivability solutions Many enterprise branch offices require survivability of basic voice services when connectivity to a centralized or local UC&C system becomes unavailable, such as when WAN connectivity is lost. For survivability in a Microsoft Lync topology, a survivable branch appliance (SBA) is used to provide intra-office instant messaging, voice calls, video, and PSTN access in cases of WAN failure. This provides all the benefits of a SIP media gateway plus survivability for Lync users at the branch. The HP MSR SBMs run Microsoft SBA software on an HP MSR Open Application Platform (OAP) module that is installed on an HP MSR30 or HP MSR50 Router Series. Together with the SIP media gateway functionality built-in the router and HP MSR Voice Modules added onto the router chassis, the HP MSR SBM provides a complete branch office survivability solution for Microsoft Lync.

• Microsoft Lync SBA software runs on HP MSR OAP module • Various HP MSR OAP modules for scalability – Small – Medium – Large • Analog device to PSTN FXS to FXO 1-to-1 mapping – Line relay when power fails (on all FXS modules that include FXO) – MSR relays FXS to FXO connection to PSTN physically when power fails – Available for each FXO port connected to PSTN • Survivability for Microsoft Lync deployments – Microsoft Lync survivability • HP MSR SBMs – Local PSTN backup on WAN failures • Simplicity

Reference designs

Reference designs provide specific examples of solutions of reference design models. Midmarket solutions Midmarket solution with SDN The reference design for a midmarket solution with SDN is based on a single campus with one building. This is an example of a small 2-tier campus solution with media gateways using elements of HP FlexCampus, HP FlexBranch, HP FlexManagement, and HP FlexNetwork UCRA with Lync reference architectures. The key features of this solution include:

• Dynamically assign QoS policies with HP Network Optimizer and HP VAN SDN Controller • 2-tier design at campus location • HP 8200 zl Series as campus core switch • HP HSR Series as campus core router • Microsoft UCOIP qualification as enhanced SIP media gateway using HP MSR Router Series • HP 3800 Series as remote site/branch office access switches • HP 4110 and HP 4120 IP Phones for Microsoft Lync A scalable and resilient SDN-enabled HP 8200 zl Switch Series is used at the core in a 2-tier campus solution that supports OpenFlow. The core switch connects to the campus router for WAN and Internet connectivity. For access switches at the campus location, the HP 3800 Switch Series is used to provide basic layer 3 Gig PoE+ client connectivity with support for OpenFlow. The campus router is based on a scalable, modular, and resilient HP HSR6600 Router Series. In addition, the HP MSR20/30/50 Series is qualified with Microsoft UCOIP to function as an enhanced SIP media gateway with Microsoft Lync. In this capacity, local analog devices connect to the HP MSR Router Series using FXS ports and access to the PSTN is provided through ISDN BRI, FXO, E1, and T1 voice interfaces using standard protocols such as ISDN and Q Signaling (QSIG). The following diagram illustrates this reference design.

Midmarket solution for 2,500 users The reference design for a 2,500-user midmarket solution is based on a main HQ campus, three other geographically dispersed campus locations with one building each and three remote site/branch office types with two of each. This is an example of a small 2-tier campus and small 1-tier branch solution with media gateways using elements of HP FlexCampus, HP FlexBranch, HP FlexManagement, and HP FlexNetwork UCRA with Lync reference architectures. The key features of this solution include:

• 2-tier design at campus locations • 1-tier design at branch office locations • HP 10500 Series as campus core switches • HP HSR Series as campus core routers • HP MSR Series as remote site/branch office routers • Microsoft UCOIP qualification as enhanced SIP media gateway using HP MSR Router Series • HP 2530 Series as remote site/branch office access switches • HP 2920 Series as remote site/branch office access switches • HP 4110 and HP 4120 IP Phones for Microsoft Lync

At the campus locations, a modular, scalable, and resilient HP 10500 Switch Series is used at the core in a 2-tier campus solution. This reference design has cost overriding redundancy, so there is one HP 10500 Series deployed as a core switch at each location for connecting servers, network equipment, and clients. The core switch connects to the campus router for WAN and Internet connectivity. For access switches at the campus location, the HP 5500-EI Switch is used to provide layer 3 Gig PoE+ client connectivity. Note that this reference design presents an all-Comware alternative upper-level small campus solution and that the HP 8200 zl/3800 Series can be used instead of the HP 10500/5500 Switch Series used in this 2,500- user solution.

37 Architecture guide | HP FlexNetwork unified communications reference architecture with Microsoft Lync

The campus router is based on a scalable, modular, and resilient HP HSR Router Series that provides WAN connectivity. For media gateway connectivity at the campus locations, the HP MSR Series is used because it is qualified with Microsoft UCOIP to function as an enhanced SIP media gateway with Microsoft Lync. In this capacity, local analog devices connect using FXS ports and access to the PSTN is provided through ISDN BRI, FXO, E1, and T1 voice interfaces using standard protocols such as ISDN and QSIG using an HP MSR Router Series. The diagram here illustrates this reference design. Figure 30. HP FlexNetwork UCRA with Lync midmarket 2,500-user reference design

At the branch office locations, a simple small 1-tier design is used. Each of the branch office locations requires media gateway access and survivability for the Lync users if the WAN is not available. The HP MSR SBM for Microsoft Lync provides the survivability functionality while the HP MSR30 Router Series hosts the interfaces used for the media gateway access. The small HP MSR SBM model is selected based on the branch office sizing. Each branch office in this reference design is slightly different, with an HP MSR30-10 Router Series and HP 2530 Switch Series paired together for a small, cost-effective branch office solution. An HP MSR30-16 Router Series is paired with an HP 2920 Switch Series to provide an alternative solution that might require basic layer 3 for a small 1-tier branch office. An alternative small branch office solution is illustrated with an HP MSR30-20 Router Series paired with an HP 5120-EI Switch Series for an all-Comware small branch office solution.

Enterprise data center and campus solutions Enterprise solution for 5,000 users The reference design for a 5,000-user enterprise solution is based on a main HQ/data center campus location, with 4 other types of geographically dispersed campus locations with 1 building each. This is an example of a 2-tier campus solution with media gateways using elements of HP FlexCampus, HP FlexManagement and HP FlexNetwork UCRA with Lync reference architectures. At this sizing, the reference design uses HP FlexCampus reference architecture at the HQ/data center campus location. The key features of this solution include:

• 2-tier design at campus locations • HP 10500 Series as HQ/data center campus core switch—due to sizing and HQ/campus requirements • HP 5500-EI Series as access switch • HP MSR Router Series as Microsoft UCOIP qualified enhanced SIP media gateways • HP MSR SBM Series for Microsoft Lync remote site survivability • HP 8200 zl/3800 Series at some campus locations • HP 10500/5500-EI Series at other campus locations • HP 4110 and HP 4120 IP Phones for Microsoft Lync

Based on the HP Networking FlexCampus reference architecture, at the HQ and campus locations a 2-tier optimized network is designed using HP 10508 Switch Series core and HP 5500 EI Access Switches. In the 2-tier HP optimized design, switch and link aggregation technologies are implemented to increase the number of ports and achieve redundancy while reducing protocol complexity. The core is implemented using a HP 10500 Switch Series IRF Fabric. In the case of the access switches, a HP 5500 EI Switch is used to provide advanced layer 3 functionality along with IRF switch aggregation. The campus router is based on a scalable, modular, and resilient HP HSR Router Series that provides WAN connectivity. For media gateway connectivity at the campus locations, the HP MSR Series is used because it is qualified with Microsoft UCOIP to function as an enhanced SIP media gateway with Microsoft Lync. In this capacity, local analog devices connect using FXS ports and access to the PSTN is provided through ISDN BRI, FXO, E1, and T1 voice interfaces using standard protocols such as ISDN and QSIG using an HP MSR Router Series.

Standalone router branch office The reference design for an enterprise standalone router branch office solution is based on a branch office with a single router device that enables convergence of LAN, WAN, virtualization, and other services, but also requires local analog device connectivity or PSTN access. The voice component of the solution is provided by the HP MSR Series as an enhanced SIP media gateway, with the particular model selected based on interface type, capacity, performance, and resiliency characteristics. In this reference design, there is no requirement for remote site survivability, but it must be supportable and installable at a later date. The key features of this solution include:

• Requires local analog device (FXS) and PSTN connectivity using FXO, ISDN-BRI S/T, E1-voice, or T1-voice interfaces • No requirement for remote site survivability, but needs to have capacity to support it later • Ideal for small sized remote sites/branch offices • Better suited for small number of users • Converge virtualization and other services on a modular router • Central or distributed managed wireless 802.11n access—separate component, not built-in • Optional 4G-LTE/3G as primary or secondary WAN access • PoE • HP 4110 and HP 4120 IP Phones for Microsoft Lync
