6WIND* and Intel®: Delivering High-Performance Software-Based IP and Ipsec Routing WHITE PAPER 6WIND* and Intel®: Delivering High-Performance Software-Based IP and IPsec Routing Introduction Communications service providers, cloud service providers, and enterprises are in the midst of a significant network architecture transformation as they increase the amount of IP routing and security they use, while at the same time reducing their costs. To do that, they are increasingly adopting software-based routing. While the economic advantage of this approach is substantial – Intel® architecture servers replace dedicated hardware and can drive down the cost per gigabit by up to 80% 1 – many first-generation software routers didn’t offer the performance needed for today’s network applications. In fact, the performance from Linux*- based routers wasn’t enough to fill a 10 Gbps network connection.2 That’s why 6WIND* developed the Speed Series* for Intel platforms – a 200 Gbps IP router, the industry’s first 100 Gbps IPsec software solution, and a software platform for wire speed virtual infrastructure acceleration. The Speed Series is based on 6WINDGate*, a high-performance packet processing software solution. 6WIND also leverages the power of Intel® Xeon® servers and collaborated with Intel on technologies such as the Data Plane Development Kit (DPDK) that are instrumental to achieving these performance levels. More IP Networks Drives Need for More Routing and Security From advanced wireless networks to the Internet of Things, the demand for IP routing and network security is growing at a very fast pace. For example, in the market for service provider routers, 2014 was a record year for the industry with aggregate revenues hitting $10 billion according the research by Dell’Oro Group. 3 The firm also predicts that this growth will continue at least through 2015 when it projects that industry sales of routers will hit $11.5 billion.4 This prevalence of IP data traffic also foretells a greater need for routing of IPsec encrypted data packets in order to protect these data flows from security threats. Many new IP applications, such as LTE base stations, cable networks, cloud 1 6Wind internal study, available on request under NDA 2 6WIND Turbo Router + 6WIND Virtual Accelerator vs. Linux Routing + Open vSwitch. https://www.youtube.com/watch?v=icvVqvvrVeA The test platform for these results was a server using a 2.8GHz Quad Intel Xeon E7-4890 v2 with 128 Gigabytes of RAM and equipped with 10 dual-port 10GbE Intel network controllers. 3 Demand for Service Provider Routers Grows to Almost $10 B in 2014, According to Dell’Oro Group See more at: http://www.delloro.com/news/demand-service-provider-routers-grows-almost-10-b-2014-according-delloro-group#sthash.M8v9gwMm.dpuf 4 Service Provider Router Market to Exceed $11.5 Billion in 2019, According to Dell’Oro Group Forecast See more at: http://www.delloro.com/news/service-provider-router-market-exceed-11-5-billion-2019-according-delloro-group-forecast#sthash.DailEIGk.dpuf 2 6WIND* Intel® Network Builders White ˜aper Table of Contents computing, and others, have not had a 24-core Intel® x86 server to deliver a the need for security, thus they are not throughput of 7 Gbps.2 This is used to the cost and extra hardware acceptable performance for 1 Gbps Introduction .......................1 needed to provide high-performance network applications, but cannot scale More IP Networks Drives Need IPsec encryption. to support the 10 Gbps and 40 Gbps for More Routing and Security ......1 networks that are growing in popularity.

  • MANO-Deployed Virtual Router Simplifies Network Deployments
    SOLUTION BRIEF Communications Service Providers Virtual Routers MANO-Deployed Virtual Router Simplifies Network Deployments 6WIND,* Advantech,* and Cloudify* create virtual routers with simplified deployment and lifecycle management to scale networks. Italian CommSP EOLO* utilizes this solution to create a backbone mesh connecting thousands of wireless base stations. Virtual routers provide the functionality of legacy, fixed-function routers with more flexibility and lower cost. The next step for communications service providers (CommSPs) who have embraced this technology and are deploying thousands of these virtual network functions (VNFs) throughout their network is to add management and network orchestration (MANO) features that can provide better configuration, deployment, and lifecycle management functions to all of the vRouters in a network. 6WIND,* Cloudify,* and Advantech*—all Intel® Network Builders ecosystem partners—have integrated their technologies to provide a MANO-deployed vRouter solution. vRouters Need MANO A virtual router is a virtual network function (VNF) application that runs on commercial off-the-shelf (COTS) server platforms and replaces legacy routers that run on fixed-function hardware appliances. The use of COTS servers typically makes vRouters less expensive to purchase, while the remote deployability and life cycle management of software-based vRouters reduces the cost to operate routed networks. Virtual router companies like 6WIND have made significant progress on evolving vRouter software. With new Intel® Xeon® Scalable processors and packet forwarding technology such as the open source Data Plane Development Kit (DPDK), vRouters can offer the outstanding performance that CommSPs require.¹ Now, 6WIND is tackling the challenge of mass deployment and management of vRouter networks by working with MANO software from Cloudify.

  • 6WIND Boosts Ipsec with Intel® Xeon® Scalable Processors
    SOLUTION BRIEF Communications Service Providers IP Security 6WIND Boosts IPsec with Intel® Xeon® Scalable Processors Tests of 6WIND Turbo IPsec show up to a 50% performance improvement when run on a server powered by the Intel® Xeon® Platinum 8170 processor.1 Introduction IP security (IPsec) is a critical element for every IP network to help protect against cyberattacks and provide data confidentiality, privacy, and security. Mobile network operators (MNO) and data centers are adopting bare metal and virtualized IPsec solutions on Intel servers to realize scalability and efficiency while lowering costs. Server performance is a critical issue in effective bare metal and virtualized IPsec solutions, and the Intel® Xeon® Scalable processors offer new options for next-generation networks. To test the new processors, Intel® Network Builders ecosystem member 6WIND set up two use cases for its 6WIND Turbo IPsec™ virtualized software. The Challenge To evaluate the performance of Intel Xeon Scalable processors, 6WIND selected its two most popular customer use cases to test the 6WIND Turbo IPsec VNF. Security-Enabled Site-to-Site Virtual Private Networks (VPNs): IPsec virtual private networks (VPNs) are critical to wide area network infrastructure to create security-enabled, high-speed communications tunnels between trusted endpoints. Examples include linking data centers and remote sites in a corporate network. Since IP WANs should be considered inherently insecure, IPsec VPNs maintain data confidentiality and integrity through encryption techniques, and they must provide scalable throughput to avoid bottlenecks that can force data centers to choose performance over security. For example, poor performance can translate to a loss of customers in multi-tenant data centers.

  • Intel and Red Hat Demonstrate SDN Service-Chaining Solutions
    White Paper Intel® Open Network Platform Software Defined Networking Division Going Virtual: Intel and Red Hat Demonstrate SDN Service-Chaining Solutions As software-defined networking (SDN) and network function virtualization (NFV) have gained traction in the marketplace, many organizations—from enterprise IT to cloud and telecommunications service providers—have discovered the benefits of virtualizing compute and networking components. Enterprises and service providers face intense pressure to support the rapid deployment of new services, and this is one of the key factors driving the industry shift to SDN and NFV solutions. Service chaining adds another dimension to virtualization possibilities: added flexibility in integrating virtual appliances into the mix to handle routing, switching, and other functions as part of the service chain. Service chaining provides a flexible means of managing network traffic more intelligently—with greater agility—when moving from physical networking machines, such as routers and switches, to virtual network appliances that implement multiple virtual machines on each standard high-volume server (SHVS). To advance this technology further, the Intel® Open Network Platform (Intel® ONP) reference architecture and Red Hat’s Enterprise Linux* OpenStack* platform, combined with open-source components and virtual appliances from Intel® Network Builders partners, form the basis of a powerful demonstration that shows the practical capabilities of service chaining in action. This paper explains the concepts that characterize service chaining and discusses the multi-vendor demo that illustrates the benefits of this technology to enterprises, cloud, and telecommunications companies.
