Cisco unveils CRS-X addition to its core router family

Created September 10, 2013
Technologies and Products

Cisco continues to enhance its core router product line with the announcement of the Carrier Routing System-X (CRS-X). Available later this year, the CRS-X is a 400Gbps per interface slot system that can be expanded to nearly 1 petabit per second in a multi-chassis deployment. That’s 10 times the capacity of the original CRS-1 platform, which was introduced in 2004.

The system will use the company’s internally developed CPAK 100G optical transceivers. Each 400-Gbps line card will use Cisco AnyPort technology to allow network operators to configure the interfaces on the card. Operators can mix and match interface rates (10 Gigabit Ethernet (GbE), 40 GE, and 100 GE) and distances (short reach, extended reach and long reach) on the same line card.
Cisco also says it will provide a choice of integrated optics or the new Cisco Network Virtualization (nV) “optical satellite.” Both are powered by Cisco’s nLight technology for control plane automation. The nV configuration allows operators to configure physical CRS-X chassis with satellite optical transmission systems via a shared control plane.
The CRS-X has also been designed to give Cisco’s existing CRS-1 and CRS-3 system customers an upgrade path – there are over 1000 CRS multichassis systems in operation around the world, the company says. Existing customers can upgrade to the new platform with minimal traffic impact via in-service replacement cards, or by adding CRS-X chassis to existing multi-chassis deployments.
That feature seems to be appreciated. “The Cisco CRS provides Verizon Wireless with an intelligent core solution and the ability to scale up to 400 Gbps per slot, which will meet our service demands well into the future,” said Mike Haberman, vice president of network operations, Verizon Wireless, in Cisco’s press release.
Cisco’s news wasn’t unexpected, given that several competitors already have 400Gbps per slot systems on the market. In fact, unless the company announces an upgrade within the next six months, Juniper will become the only one of the top four core router vendors not delivering 400Gbps-per-slot capacity in its core router product, points out David Krozier, principal analyst, network infrastructure, in an analyst note.
