Cisco CRS-3 Modular Services Card Expansion module for P N: CRS-16 S, CRS-4 S, CRS-8 S

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 Cisco CRS-3 Series Modular Services Card provides distributed forwarding engine capability for the Cisco CRS family. Optimized for high-speed edge applications, it provides massive VLAN scale and wire-rate hierarchical quality of service (QoS). 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, 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.
