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).

Features and Benefits

Cisco CRS forwarding processor cards offer many advantages:

●   Support across multiple Cisco CRS form factors, including 8-slot, 16-slot, and multichassis

●   Forward and backward compatibilities; the Cisco CRS-1 (40 Gbps), CRS-3 (140 Gbps), and CRS-X (400 Gbps) cards can coexist on the same chassis when using the Cisco CRS-X fabric

●   Up to 400-Gbps line-rate throughput per slot, increasing the Cisco CRS capacity to 12.8 Tbps in a single chassis

●   Occupies one-half slot, allowing the card to be paired with a variety of interface modules, providing deployment flexibility (Cisco CRS-FP400G and CRS-FP140 only)

●   Layer 3 forwarding engine with industry-leading, wire-rate performance

●   Built-in hardware acceleration for critical network-control traffic

●   Accurate hardware-assisted time-stamping support for service-level agreement (SLA) monitoring

●   Energy monitor functionality that allows real-time power monitoring of each individual component, including physical layer interface modules (PLIMs) and line cards, fabric, Performance Route Processor (PRP) through Command Line Interface (CLI), beginning with Cisco IOS^® XR Release 5.1.1 (Cisco CRS-FP400G)
