Cisco Ships 900 CRS-1s in First Three Years to Drive Residential and Business IP Service Growth


Cisco® announced today that it has shipped 900 of the industry-leading Carrier Routing System (CRS-1), the core component of the Cisco Internet Protocol Next-Generation Network (IP NGN) architecture, to more than 85 providers since the first product shipment in August 2004. The CRS-1 offers providers a cost-effective means to meet the performance and reliability requirements of advanced service delivery while accommodating ever-increasing IP traffic.

The rapid growth of CRS-1 sales has been both accompanied and, to some degree, driven by significant IP traffic growth on global networks as video and other advanced service deployments continue. According to data compiled by Cisco and industry analysts, Internet video produced six times more IP traffic in 2006 than the amount of IP traffic that crossed the entire U.S. Internet backbone in 2000. By 2011, global IP traffic is projected to reach more than 26 exabytes per month (an exabyte is a unit of information or computer storage equal to one quintillion bytes).

BT and Sprint are among the leading global providers that have deployed the Cisco CRS-1 as the foundation of their IP transformation initiatives.

“The consolidation of BT’s various service-specific networks onto a single IP infrastructure, combined with the growth of Internet traffic due to advanced services like IPTV and collaboration, makes having a reliable, highly-scalable, IP/MPLS core critical,” said Matt Bross, Group CTO at BT Group. “Our aggressive 21CN service strategy, driven by the growing needs of our residential, business and industry customers, will increase traffic growth and we wanted to deploy a core routing system that would meet those needs now and in the future.”

“We are deploying the Cisco CRS-1 to support our dramatic growth in MPLS services including our action to migrate customers from legacy non-IP-based technologies to our SprintLink IP and Global MPLS platforms,” said Iyad Tarazi, vice president of network development for Sprint. “In addition to our wireline investments, we expect to see exponential growth in wireless data for 3G and Wi-Max services which also require significant investments in our IP core. The CRS-1 is well-suited to meet our needs, thus allowing us to support the long-term needs of our customers.”

Other publicly announced CRS-1 customers include Cable & Wireless, Comcast, China Telecom (ChinaNet), China Education and Research Network (CERNET), Deutsche Telecom, Korea Telecom, FREE, the National Institute of Informatics’ SuperSINET research network in Japan, Neuf Cegetel, National LambdaRail, MTS Allstream, MTN, Pittsburgh Supercomputing Center(PSC), SaskTel, Savvis, Softbank, Yahoo! BB, Swisscom, Shanghai Telecom, Strato Medien, Teliasonera, Terremark, Telstra and VTR.

The Cisco CRS-1 is the industry’s most powerful carrier routing system, designed with the aim of offering continuous system operation as well as unprecedented service flexibility and scalability. Powered by Cisco IOS XR Software, it is designed for always-on operation while scaling system capacity up to 92 terabits-per-second (Tbps). The innovative system architecture combines the Cisco Silicon Packet Processor, the first programmable 40-Gbps ASIC, with the Cisco Service Separation Architecture for unprecedented service flexibility and speed to service. The CRS-1 marks a new era in carrier IP communications by powering the foundation for IP NGNs today while protecting investments for decades to come.

Cisco CRS-1 milestones:

September 2006 - Four-slot CRS-1 joins the 16-slot platform 1.2 Tbps and the eight-slot platform (640 gigabits per second), all of which feature cross-slot-compatibility for continued investment protection.

February 2006 - CRS-1 supporting 40Gbps OC-768c service is deployed in production network (Yahoo! BB, Japan)

January 2006 - Shanghai Telecom becomes first provider to use multichassis CRS-1

December 2005 - CRS-1 delivers industry-leading IP over dense wavelength-division multiplexing (IPoDWDM) optical integration

July 2005 - CRS-1 sets Guinness world record with the world’s highest-capacity Internet router

December 2004 - Cisco announces availability of eight-slot CRS-1

May 2004 - Cisco announces CRS-1 16-slot availability

“CRS-1 deployments continue to expand as providers accelerate their migrations towards IP Next Generation Networks to deliver advanced voice, video and data services,” said Tony Bates, senior vice president and general manager of the service provider technology group at Cisco. “We are extremely pleased with the CRS-1’s rate of adoption in the market, but possibly even more so with what it demonstrates - that the network is indeed the platform for changing how we live, work, play and learn.”
