The Cisco CRS-3 Forwarding Processor Card provides distributed forwarding engine capability for the Cisco CRS family. It is responsible for data-plane processing tasks, handling all network traffic flows through it. The 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. The performance highlights of the card include hardware-assisted policing, and jitter- and latency-minimizing multicast packet replication.
