Cisco CRS Forwarding Processor Cards
Product Overview
The Cisco
®
Carrier Routing System (CRS) provides outstanding economical scale, IP and optical network
convergence, and a proven architecture. The Cisco CRS continues to evolve with the needs of the network,
becoming more elastic and programmable. As part of an evolving and programmable network, the Cisco CRS
delivers highly reliable operations and scales easily from a single-chassis to a massive multichassis system.
The Cisco CRS design offers industry-leading efficiency in power consumption, cooling, and rack-space resources,
while providing intelligent service-rich bandwidth capacity.
Cisco CRS forwarding processor cards provide distributed forwarding-engine capabilities and scalability, which are
important for supporting the Internet of Everything. The Cisco CRS forwarding engine is responsible for data-plane
processing tasks and handling all network traffic flows through the system. The forwarding processor 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 Cisco NetFlow. Performance
highlights of the forwarding processor cards include hardware-assisted policing and jitter- and latency-reducing
multicast packet replication.
Cisco CRS forwarding processor cards include the Cisco CRS-X 400-Gbps Forwarding Processor Card, Cisco
CRS-X Series 200-Gbps Lite Forwarding Processor Card, Cisco CRS-3 140-Gbps Forwarding Processor Card
(Figure 1), and the Cisco CRS-1 Series 40-Gbps Forwarding Processor Card (Figure 2).
