Private IP Overview Private IP Overview Private IP is a network-based virtual private network (VPN) enabling customers to effectively communicate over a secure network. It also provides the foundation for automating business processes between companies, including e-commerce, shared intranets, and extranets. Private IP: Is based on Layer 3 Multiprotocol Label Switching (MPLS), which enables Private IP to separate customer traffic through a VPN, resulting in the security and Quality of Service (QoS) of Layer 2 switching with the scalability and any-to-any connectivity of IP. Is available as a non-managed transport or as a Managed Services solution. Non-managed transport customers can use the Remote Configuration feature to outsource implementation to Verizon in specified markets. Standard service offers Internet Engineering Task Force (IETF) Differentiated Service (DiffServ) class of service. Private IP's Enhanced Traffic Management (ETM) enables customers to prioritize their traffic and assign classes of service distinguished by different levels of packet loss and jitter. Offers advanced network assessment, reporting, dynamic bandwidth, and packet marking tools, allowing customers to fine-tune their networks to improve performance, gain visibility, and achieve new levels of cost-efficiencies. Supports a full range of access types. Features and Benefits Feature Description Benefit to the Customer Scalability Ease of expanding the network. Customers can expand their networks to higher speeds or to multiple locations in a fully meshed environment with little disruption.

The tools empower the customer to take control of their bandwidth. Looking Glass Looking Glass is part of the Application Aware virtual private network (VPN) suite of solutions. This application is an empowerment tool for customers, providing them with the ability to view the configuration information of their Private IP VPN via the Verizon Enterprise Center portal. Private IP customers who are not using Dynamic Bandwidth can use the Looking Glass tool to see their network attributes and determine how their sites are configured at the Provider Edge (PE) devices on the network. Private IP only customers can also see if a port or CAR change submitted to their Verizon Account Team has been completed. The tool allows customers to download sample configurations for their CE router. Private IP customers will be able to use this tool in conjunction with Dynamic Bandwidth to see/validate that their orders have been completed and their configurations changed through the Dynamic Bandwidth tool. Following are the items the customer can view: VPN Level Information Class of Service Information VPN Name Class of Service (CoS) type (Private IP VPN Default Standard or Private IP Enhanced Traffic Multicasting VPN (True/False) Management) Multicasting Rendezvous Point Address Gold CAR VPN Topology (fully meshed/hub and Silver CAR spoke) Multicasting CAR Max Routes Concord Enabled VRF Parameters Maximum paths VRF Name Enhanced Interior Border Gateway Router name Protocol (EIBGP) Load Sharing Hub/Spoke Routing Protocol Max Routes Border Gateway Protocol (BGP) CE AS eHealth Enable flag Num Max Paths BGP Message-Digest algorithm 5 (MD5 Multicasting Rendezvous Point (RP) Address password) BGP Timers keepalive BGP Timers hold time BGP Send community Site Information BGP Routing Information Site Name Allow Autonomous System (AS) Circuit ID AS override Permanent Virtual Circuit (PVC) ID CE AS Number Location Timers keepalive PE Interface Timers hold time Router name Routing Information Protocol (RIP) Routing Router type Information Speed Redistribute OSPF (Open Shortest Path First) Interface name OSPF PE IP Address/Prefix Length VPN Level Information Class of Service Information Fragmentation Private IP Static Routes Multicasting site type (hub or remote) Destination Address Encapsulation (diff from CE indirect) Destination subnet mask Access Type (e.g. T1, E1, T3, etc.) Forwarding address Customer Edge (CE) Interface Site of Origin information Information Connection Type (Direct/Indirect) Site of origin site type CE IP Address/Prefix Length Remote site order number Encapsulation Data Link Connection Identifier (DLCI), Virtual Path Identifier (VPI), or Virtual Local Area Network (VLAN) ID Router model (for managed only) Router DNS domain ID (this is the ESP identifier for the managed device) The Looking Glass Tool will allow customers to make changes to the following items without incurring an additional charge. This will eliminate customers from having to request these changes through their Account Manager. Customers will be able to select the "Modify" option next to the field that can be changed. Private IP Customers will be able to create a Looking Glass order to change the following parameters: Routing Protocol Admin Status Shaping Adjust These orders can be cancelled once they have been submitted but prior to completion, if the customer determines the change are not appropriate. Customers who have subscribed to WAN Analysis Reporting can use the Looking Glass application to link them right over to the WAN Analysis portal. Customers will have to log into the WAN Analysis portal using their user ID and password. This will allow customers to toggle between the two tools to adjust any bandwidth as needed. Reporting WAN Analysis WAN Analysis Reporting offers customers a one-stop solution for proactive performance management, capacity analysis and reporting on their network infrastructure. WAN Analysis Reporting provides customers with a single view of their infrastructure by consolidating reporting for selected Verizon transport (e.g., Private IP, Private IP Satellite) and Verizon managed network services (e.g., Managed WAN, Managed LAN). WAN Analysis Reporting is powered by CA eHealth, CA Report Analyzer and CA Performance Center software which is provided and managed on behalf of Verizon by CA Technologies. CA is a Fortune 500 company and one of the larger independent global software corporations. CA eHealth, CA Report Analyzer, and CA Performance Center are part of CA's portfolio of infrastructure management services, which also includes CA Spectrum Infrastructure Manager. WAN Analysis Reporting uses the Simple Network Management Protocol (SNMP) to periodically query the management information base (MIB) of customer premises equipment (CPE). The data collected is related to device configuration and device component performance. The process of periodically querying the MIB of a device is referred to as "polling." Polling reduces the load (such as bandwidth utilization) on customer networks but the tradeoff is that performance information is slightly delayed due to the interval between individual polls. In addition, the WAN Analysis ETM Select

  • Qos Support in MPLS Networks
    1 QoS Support in MPLS Networks MPLS/Frame Relay Alliance White Paper May 2003 By: Victoria Fineberg, Consultant [email protected] Abstract MPLS is sometimes used synonymously with QoS, but more accurately, it is a QoS- enabling technology that forces application flows into connection-oriented paths and provides mechanisms for traffic engineering and bandwidth guarantees along these paths. Furthermore, when an MPLS network supports DiffServ, traffic flows can receive class- based admission, differentiated queue servicing in the network nodes, preemption priority, and other network treatment that provide bases for QoS guarantees. The IETF work in this area has been augmented by the MPLS/Frame Relay Alliance Implementation Agreement which extends MPLS to the user-network interface, and thus serves as a foundation for implementing QoS end-to-end. This paper describes various QoS and MPLS mechanisms and analyzes their applicability. 2 Table of Contents 1.

  • The Role of Emerging Broadband Technologies on the Converged
    The Role of Emerging Broadband Technologies on the Converged Packet-Based Network Introduction The vision of network convergence toward a consolidated packet-based network has been discussed for years, though it is still not a reality. Currently, there are numerous overlay networks such as IP, ATM, FR, Ethernet, SONET, DWDM and wireless for different services. The evolution pace toward convergence has been slow due to economic, technical and regulatory issues. However, the fact is that data traffic volume is now surpassing voice traffic volume. Traditional TDM voice traffic is moving to IP packets and TDM private line is moving to Ethernet private line. The wave of broadband applications such as Internet access, VOD, and IPTV create high bandwidth requirements for the network. These applications are packet-based, but have a much lower margin of profit for the service providers when compared to traditional voice service. Today’s overlay and traditional circuit-based infrastructure will become less optimal for the new packet-based services as the profit margin decreases. Most of the wireless networks in North America today are still circuit-based because most of the current wireless service is still voice-based. However, with emerging wireless access technologies such as WiMAX and Wi-Fi, more broadband wireless data and video services can be deployed. As a result, the wireless core network evolves toward a packet-based network. Service offerings drive network evolution. As more packet-based broadband services are launched and bundled together in service offerings, service providers start to add more packet-aware features into their current network components.

  • VPLS: the Switched Ethernet
    VPLS: The Switched Ethernet Executive Summary VPLS is becoming a popular networking option. Its inherent Ethernet any-to-any connectivity model makes VPLS a popular choice for enterprises adding or deleting sites. Existing Ethernet users may have a simple implementation by modifying existing Ethernet equipment, which will also scale easily to meet future bandwidth needs. Although it has many advantages, VPLS may not be right for every business. This paper explains VPLS and discusses when it is a good networking solution.

  • Vlans Feature Overview and Configuration Guide
    TechnicalTTechnicalechnical GuideGuidGuidee Virtual LANs (VLANs) Feature Overview and Configuration Guide VLAN Introduction This guide describes Virtual LANs (VLANs), VLAN features and configuration on the switch. It begins with a description of what a VLAN is, its evolution and purpose, and also provides the meaning of some common VLAN terminology. This is followed with a detailed look at VLAN implementation. Port-based VLAN membership is the most common way to split a network into sets of virtual LANs. We look at how this is achieved using the VLAN tagging. The use of double-tagging (or VLAN stacking) to tunnel VLANs across Layer 2 networks is described, and an example is provided for the configuration of VLAN stacking. Next we discuss private VLANs and the communication rules that limit what is possible between devices operating within the VLAN. AlliedWare Plus™ has two private VLAN solutions: private VLANs for ports in Access Mode private VLANs for ports in Trunked Mode Configuration examples are provided for both of these solutions. Then, we look at combining private VLANs with other features, such as: EPSR, ARP, LLDP, GVRP, Link aggregation, and management servers. The guide ends with a section on configuring protocol based VLANs and then describes how data counters are used to count both the number of received frames or the number of received bytes (octets) belonging to a particular VLAN.
