SAN JOSE, CA–( EMWNews – April 1, 2008) – Cisco (NASDAQ: CSCO) today announced a major

sales milestone for the industry-leading Carrier Routing System (CRS-1),

the core platform for the Cisco® Internet Protocol Next-Generation

Network (IP NGN) architecture. Driven by increased network, service and

application convergence to facilitate delivery of video services, total

worldwide cumulative shipments of this platform have doubled in less than

nine months, rising from a total of 900 units shipped through June 2007 to

more than 1,800 units shipped through March 2008.

“Exponential traffic growth on the Internet — driven largely by increased

deployment of video services — is causing more and more providers to

rethink their core architectures,” said Michael Howard, principal analyst

at Infonetics Research. “Highly scalable, reliable and intelligent core

platforms such as the Cisco CRS-1 help providers meet their needs, as

business and residential consumers demand more video content in

increasingly personalized bundles.”
