Cisco CRS-MSC-20G : Cisco CRS-1 Series Modular Services Card 20G

The Cisco® CRS-1 Carrier Routing System is the industry's first carrier router offering continuous system operation, 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. The innovative system architecture combines the Cisco Silicon Packet Processor, the first programmable 40-Gbps application-specific integrated circuit (ASIC), with the Cisco Service Separation Architecture for unprecedented service flexibility and speed to service. The Cisco CRS-1 marks a new era in carrier IP Communications by powering the foundation for network and service convergence today while protecting investments for decades to come.


The MSC-B offers many advantages-

• Supported across all the CRS-1 form factors: 4-slot, 8-slot, 16-slot and Multi-chassis

• Powered by the Silicon Packet Processor (SPP), one of the world's most sophisticated 40 Gbps ASIC

• Features two Silicon Packet Processors (SPP)- one for ingress, one for egress packet handling

• Always paired with Interface Module (IM) through the chassis mid-plane, thus occupying one-half of a slot.

• Can be paired with a variety of Interface Modules (IM) providing deployment flexibility

• Layer 3 forwarding engine of the CRS-1 with an industry leading wire rate performance at 40 Gbps

• Additional services of Class of Service (COS) processing, Multicast, Traffic Engineering (TE), including statistics gathering, are also performed at 40Gbps line rate

• Supports several forwarding protocols, including IPv4, IPv6, and MPLS

• Enhanced performance with hardware based prefix lookup for IPv4, IPv6, and MPLS

• Better environmental features with a lower power and weight profile
