The Cisco® CRS-1 Carrier Routing System is the industry's first carrier router offering continuous system operation, unprecedented service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS® XR Software-a unique self-healing, distributed operating system. As part of a video-enabled IP Next-Generation Network (NGN), the Cisco CRS-1 Series delivers continuous, always-on operation that easily scales to support the massive bandwidth requirements of visual networking experiences such as high-definition IPTV and Cisco TelePresence. These services demand a platform that delivers predictable forwarding performance and efficient, intelligent fabric-based multicast replication. The Cisco CRS-1 Series enables the Internet and NGNs to handle the approaching zettabyte era of carrier IP communications while protecting network investments for decades to come.
Product Overview
The Cisco CRS-1 Series Forwarding Processor 40G card provides 40-Gbps distributed forwarding-engine 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.
This data sheet provides detailed product specifications for the Cisco CRS-1 Series Forwarding Processor 40G card (Figure 1).

Key Features and Benefits
The Cisco CRS-1 Series Forwarding Processor 40G card offers many advantages:
• Supported across both the 4-slot and 8-slot Cisco CRS-1 Series chassis
• Paired with a variety of interface modules, providing deployment flexibility
• Provides Layer 3 forwarding with wire-rate performance at 40 Gbps and predictable throughput with features enabled such as Unicast Reverse Path Forwarding (uRPF) and large access control lists (ACLs).
• Additional services such as class-of-service (CoS) processing, Multicast, Traffic Engineering (TE), and NetFlow, are also performed at 40-Gbps line rate
• Supports several forwarding protocols including IPv4, IPv6, and Multiprotocol Label Switching (MPLS)
• Enhances performance with hardware-based prefix lookup for IPv4, IPv6, and MPLS
