BT tests verify the performance of Cisco CRS
San Jose, California, September 2006 – Vision Systems Cisco Carrier Routing System Fabric Cisco CRS-1 in the UK to pass all Telecommunications (BT) authentication, multicast and QoS features make the most advanced left this world years of basic high-speed routing platform as support for digital video, IPTV and other advanced telecommunications companies a powerful tool. Cisco CRS-1 is the IP Next Generation Network (IPNGN), the basic component architecture, but also for the expansion of digital video and IPTV applications, and using virtualization technology to achieve safety the best platform for network convergence.
 July of this year’s test by China, BT in a CRS-1 multi-chassis, the State Department has installed three areas of security of the router (SDR) radio and television, video on demand ( VoD) and basic applications. After testing the Cisco CRS-1 can support 400,000 simultaneous multicast streams, support for priority queuing and traffic shaping, protecting important digital video or voice over IP (VoIP) traffic, avoid Low flow by increasing the excess bandwidth when the time and packet loss rate.
 CRS-1 will not affect other operating SDR under the principle of adding new DTS, fully proved that the product does not cause interference or failure in the case of a single routing run multiple instances of capacity. This high degree of reliability and availability of digital video and IPTV delivery of critical applications.
 Daniel Percy BT network integration engineer, said: “We tested the conclusion that the implementation of SDR based on the CRS-1 is a high performance solution to help telecom operators to deliver video services complex and the current one integrated router to deploy the platform in next generation network. ”
 Synergy Research Group Ray Mota, Chief Strategist, Dr. array declared: “The digital video and IPTV services will drive the rapid flow of basic network capacity and performance, to adopt the new criteria evaluation. The Cisco CRS-1 telecom operators to provide a set of new features to support dynamic video. Therefore, the core of Cisco networking in the region has recently gained market share. ”
 BT also uses a Gigabit Ethernet IPoDWDM (dense wave division multiplexing based on Internet Protocol Contact) Interconnection to the 4-slot single chassis CRS-1 for multicast performance evaluation, found that for comparable performance multi-chassis router CRS-1 comparable.
 Ps 40Gb distributed routing ensures that operators can deploy to meet the bandwidth and increasing performance requirements, to provide digital cable TV, IPTV, VoD, and HDTV ( HDTV) and other video services. Cisco CRS-1 is based solely on industry to ensure continuous system operation, service flexibility and advanced design life of the system carrier-grade router. Cisco CRS-1 uses CiscoIOS? XR software, the unique, self-recovery of distributed operating system are designed to provide continuous operation while reducing the system capacity up to 92 Tbps.
 Cisco announced CRS-1 customers include China Telecom, China Education and Research Network (CERNET), British Telecom, Japan’s National Institute of SuperSINET research network, the Pittsburgh Supercomputing Center, Shanghai Telecom, Korea Telecom, Cable & Wireless Comcast, Easynet, National LambdaRail, MTSAllstream, SaskTel, Softbank Yahoo! BB, Strato MedienAG, Swisscom, Telstra and VTR.
 Cisco Systems vice president, general manager of core routing technology KellyAhuja said: “The Cisco CRS-1 Carrier increasingly easy to extend, highly available and flexible digital video and IPTV services, a wise choice. With its unmatched capabilities of multicast and quality of service and support of virtualization security and the advanced optical integration, there is no doubt that operators worldwide in the CRS-1 as most demanding and most advanced applications.
