| Cisco Releases Four-slot Version of CRS-1 Carrier Routing System Cisco Systems extends its CRS-1 Carrier Routing System, the core of the Internet Protocol Next-Generation Network architecture. The new four-slot version of the CRS-1 provides 320 gigabits-per-second of total switching capacity in the compact 40 Gbps-per-slot chassis, enabling deployment at regional Points of Presence, MSO hub locations and data center peering sites. This enables providers to deploy CRS-1s more broadly and at lower entry cost, allowing rapid deployment and continued expansion of IPTV, digital video and other advanced business and residential IP services. The four-slot CRS-1 joins the 16-slot platform (1.2 terabits-per-second) and the eight-slot platform (640 Gbps), all of which feature cross-slot-compatibility for continued investment protection. The Cisco IP NGN enables the development and delivery of application- and subscriber-aware services to help providers increase revenue and enhance efficiencies for improved profitability and control of their networks and business. Sprint has been evaluating the CRS-1 since 2004 and will deploy it beginning in CYQ4 2006. The new four-slot chassis will enable Sprint to deploy 40 Gbps routing more broadly and at a lower cost. Distributed deployment of 40 Gbps routing helps ensure that providers are able to meet the ever-increasing demand for delivery of video services including digital cable, IPTV, video-on-demand and high-definition television. The Cisco CRS-1 is the industry's only carrier router offering continuous system operation, and offers unprecedented service flexibility and system longevity. The Cisco CRS-1 is powered by Cisco IOS XR Software - a unique, self-healing, distributed operating system designed for always-on operation while scaling system capacity up to 92 Tbps. Publicly announced CRS-1 customers include BT, Cable & Wireless, Comcast, China Telecom, China Education and Research Network, Korea Telecom, the National Institute of Informatics' SuperSINET research network in Japan, National LambdaRail, MTS Allstream, Pittsburgh Supercomputing Center, SaskTel, Softbank Yahoo! BB, Strato Medien AG, Swisscom, Shanghai Telecom, Telstra and VTR. The Cisco CRS-1 features: * 40 Gbps routing in all form factors, supporting scaling from 320 Gbps to 92 Tbps of throughput * 100 Gbps ready * Intelligent video distribution with fabric-based IP multicast replication * Secure Virtualization using Secure Domain Routers (SDRs) to segregate and deliver advanced IP services on a common routing infrastructure to simplify network operations and reduce costs * 40 Gbps and 10 Gbps Internet Protocol over Dense Wave Division Multiplexing (IPoDWDM) Architecture for enhanced scale and efficiency * The industry's highest 10 Gbps Ethernet density, supporting from eight to 9, 216 ports on a single system * Unsurpassed investment protection, with standardized I/O modules and forwarding engines across the entire CRS-1 product family and SPA compatibility with Cisco 12000, 7600 and 7300 platforms. discuss the article write your comments about the article :: © 2006 Computing News :: home page |
