Chalk Up Another Win for CRS-1

January 31, 2006 - chalk action once again won the Cisco Systems, Inc. and its carrier-class routing system (C RS) 1. Last week, Cisco announced that the CRS - 1 has been selected by China Telecom giant Shanghai Telecom to expand its IP network and provide super POPs for its high-speed core IP networks.

Have a couple of important takeaway here, analysts said. First of all, Shanghai Telecom is Chinas first telecommunications company in the deployment of CRS - 1. More importantly, analysts say, Ciscos coup provides convincing evidence that the core capacity requirements are beginning to exceed the density of 1.2 tbps router.

"Significant positive Shanghai Telecom announced its intention to deploy the CRS multichassis - 1 is a high-profile endorsement from the existing Cisco customers to use the CRS - 1 as a platform to support expansion of the core intellectual property and expand capacity to meet the rapidly growing demand for the service. "Says Glen Hunt, a senior analyst for carrier infrastructure with the current analysis. "The Notice also indicated that more than 1.28 terabits capacity needs is the support of nominally, in a single telecommunications rack and the third is the ability of service providers to collapse multiple layers of routers and / or edge aggregation platform into a single multichassis CRSs - 1. " More and more content for hunting, the core service provider networks must support high user density, and to increase the bandwidth per user. He cited several examples, including AT T (which avici use of the thermo-chemical reaction in the core router multichassis configuration), as well as Juniper Networks company, the two companies can accommodate a maximum of 2.4 tbps capacity, t640/tx its matrix system.

At the same time, Hunter pointed out that the Cisco CRS - 1 has not yet turned into two. In this regard, he argues that it still posed a danger to those followed in the preparation of many. "Main concern relates to notice involves the following elements: relatively new CRS - 1 platform, and has not been proved, years of business operation, especially in a multichassis configuration," he comments.

That is not all, of course. "[T] he ability to collapse multiple layers of routers into a single centralized router itself might introduce new problems, such as distribution and supply of nuances," Hunter said. "[I] neodymium network migration from existing equipment to Cisco CRS - 1 will require considerable foresight because of the large demand for power and space, can accommodate full-blown the CRS - 1." -- Stephen swoyer
