The Cisco® CRS-3 Carrier Routing System offers industry-leading performance, advanced services intelligence, environmentally conscious design, and system longevity. The Cisco CRS-3 is powered by the Cisco QuantumFlow Array – a chipset architecture based on multidimensional engineering and Cisco IOS® XR Software, a unique self-healing, distributed operating system.

Packet-based data communications are being replaced by video and rich media traversing the IP Next-Generation Network (NGN) in multiple directions, straining the architectural foundations of both public and private networks serving businesses and consumers. As part of the medianet, a media-aware Cisco IP NGN, the Cisco CRS-3 delivers continuous, always-on operations and scales easily from numerous single-chassis form factors to a massive multi-chassis system. Its design provides an industry-leading efficiency consuming lowest power, cooling and rack-space resources for an intelligent service-rich bandwidth capacity. The CRS-3 builds on the CRS-1 being backward and forward compatible, protecting existing and future investments for decades to come.

This data sheet provides detailed product specifications for the Cisco CRS-3 140-Gbps Forwarding Processor Card (product number CRS-FP140). For more information about the Cisco CRS Family and other available interfaces, visit:

Figure 1.      Cisco CRS-3 140-Gbps Forwarding Processor Card

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.

The Cisco CRS-3 Forwarding Processor Card offers many advantages:

   Powered by QuantumFlow Array, one of the world's most sophisticated chipset architectures. QuantumFlow Array was engineered for the Cisco CRS Family of routers to provide higher bandwidth than competing products without any compromise on service performance

   Supported across all the Cisco CRS-3 form factors: 4-slot, 8-slot, 16-slot, and multi-chassis

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

   Scales the Cisco CRS per-slot forwarding capacity 3.5 times from 40 Gbps to 140 Gbps

   Always paired with interface module through the chassis mid-plane, thus occupying one-half of a slot

   Can be paired with a variety of interface modules, providing deployment flexibility

   Can be mixed with 40-Gbps-per-slot modules occupying other slots in the chassis

   Features two 140-Gbps forwarding ASICs for discreet ingress and egress packet handling

   Single-flow Layer 3 traffic processing at 140 Gbps in each direction

   Enhanced onboard multi-core CPU for accelerated software processing

   Optimized for peering edge and core applications

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

   Additional services such as class of service (CoS) processing, Multicast, Traffic Engineering (TE), and statistics gathering are also performed at line-rate

   Supports up to 8 queues per port

   Built-in hardware acceleration for critical network control traffic

   Built-in support for video monitoring for a rich video quality of experience (QoE)

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

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

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

   Industry-leading environmental efficiency with a lower power and weight profile than competition
