BT Testing Verifies Advanced Digital Video/IPTV Performance Capabilities of Cisco CRS-1 Carrier Routing System.SAN JOSE, Calif. -- Industry-Leading Multicast and QoS Capabilities Make World's Fastest Core Routing Platform a Clear Choice for Digital Video/IPTV and Other Advanced Service Delivery Cisco Systems(R) (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :CSCO CSCO Cisco Systems Incorporated (stock symbol) CSCO Chief Supply Chain Officer ) today announced that BT has verified the functionality of the Cisco CRS-1, the core component of the Cisco IP Next-Generation Network (IP NGN) architecture and an optimal platform for scaling digital video and IPTV (Internet Protocol TV) Also called "TV over IP," IPTV delivers scheduled TV programs and video-on-demand (VOD) via the IP protocol and digital streaming techniques used to watch video on the Internet. applications and enabling network convergence using Secure Virtualization An umbrella term for enhancing a computer's ability to do work. Following are the ways virtualization is used. Hardware Virtualization Partitioning the computer's memory into separate and isolated "virtual machines" simulates multiple machines within one physical computer. . In the test, conducted in July of this year, three Secure Domain Routers (SDRs) were established in-service on a single CRS-1 multi-chassis system for broadcast TV, video-on-demand and core applications. The test showed support for 400,000 simultaneous unique multicast streams, and support for priority queuing and traffic shaping, protecting important digital video or voice-over-IP (VoIP) traffic from increases in latency and packet loss caused by oversubscription Oversubscription The excess number of shares or bonds that investors want to buy but are not available due to high demand. in lower traffic classes. The CRS-1 was capable of creating new SDRs in-service without affecting the operation of any other SDR See software defined radio. , demonstrating an ability to run multiple instances on a single routing system without interference or failure. This reliability and availability is critical to digital video and IPTV delivery. "BT concludes that the CRS-1 SDR implementation represents a high-performance solution that can be used by service providers to deliver complex video services and converge existing router deployments onto a single next-generation platform," said Daniel Percy, Network Integration Engineer for BT. "Exponential growth in digital video and IPTV will drive an entirely new set of metrics for throughput, capacity and performance at the core of the network," said Dr. Ray Mota, Chief Strategist for Synergy Research Group. "The Cisco CRS-1 offers service providers a set of capabilities that enable the delivery of dynamic video services. As a result, Cisco has recently gained market share in the core segment." The four-slot single chassis CRS-1 was evaluated for multicast performance utilizing a 10GigE IP over dense wavelength division multiplexing See WDM. (IPoDWDM) interconnect, and was found to be comparable in performance to the CRS-1 multi-chassis router. Distributed deployment of 40 gigabit-per-second (Gbps) routing helps ensure that providers are able to meet the ever-increasing demands for bandwidth and performance needed for delivery of video services including digital cable, IPTV, video-on-demand (VoD) and high-definition television (HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates ). The Cisco CRS-1 is the industry's only carrier router designed to offer continuous system operation, advanced service flexibility and system longevity. The Cisco CRS-1 is powered by Cisco IOS(R) XR Software -- a unique, self-healing, distributed operating system designed for always-on operation while scaling system capacity up to 92 terabits-per-second (Tbps). Publicly announced CRS-1 customers include BT, Cable & Wireless, Comcast, China Telecom (ChinaNet), China Education and Research Network (CERNET CERNET China Education and Research Network ), Easynet, Korea Telecom, the National Institute of Informatics' SuperSINET research network in Japan, National LambdaRail, MTS Allstream, Pittsburgh Supercomputing Center The Pittsburgh Supercomputing Center (PSC) is a joint effort between Carnegie Mellon University, University of Pittsburgh, and Westinghouse Electric Company. PSC was founded in 1986 by its two Scientific Directors, Dr. Ralph Roskies of University of Pittsburgh and Dr. (PSC (Public Service Commission) Same as PUC. ), SaskTel, Softbank Yahoo! BB, Strato Medien AG, Swisscom, Shanghai Telecom, Telstra and VTR (VideoTape Recorder) A videotape recording and playback machine. VTR may refer to consumer MiniDV and DV recorders or to professional machines such as Betacam, DVCPRO and DVCAM. . "The Cisco CRS-1 is an increasingly obvious choice for scalable, available and flexible digital video and IPTV service delivery," said Kelly Ahuja, vice president and general manager of the core routing technology group at Cisco. "With advanced multicast and QoS capabilities, in addition to its enablement of Secure Virtualization and its industry-first optical integration, it's no wonder that providers worldwide are choosing the CRS-1 as the basis for delivery of their most advanced and demanding applications."
