Cisco Forwarding Processor

The Cisco CRS-1 Series Forwarding Processor 40G card provides 40-Gbps distributed forwardingengine capability for the Cisco CRS-1 Series. The 40G card is responsible for the data-plane processing tasks, and all network traffic flows through it. The 40G card performs all baseline packet routing operations, including Layer 3 forwarding, quality-of-service (QoS) classification, policing and shaping, security access control lists (ACLs), VPNs, load balancing, and NetFlow. Performance highlights of the 40G card include hardware-assisted policing, and jitter- and latency-minimizing multicast packet replication.
