Get industry-leading performance, advanced services intelligence, environmentally aware design, and system longevity with the Cisco Carrier Routing System (CRS). Each model uses Cisco IOS XR Software, a unique self-healing, and widely distributed operating system.

Models include:

• Cisco CRS-3, powered by Cisco QuantumFlow Array – a chipset architecture engineered in multiple dimensions of scale, services, and savings
• Cisco CRS-1, built on the Cisco Silicon Packet Processor (SPP)

Packet-based data communications are being replaced by video and rich media crossing the IP Next-Generation Network (NGN) in multiple directions. As part of a medianet, a media-aware Cisco IP NGN, Cisco CRS eases this strain on networks. It efficiently handles the multidirectional traffic of network and data center cloud interactions.

The CRS-3 builds on the CRS-1 being backward and forward compatible, protecting existing and future investments for decades to come.

CRS series supports 4,8,16 slots Single-shelf and up to 1152 slots with multishelf and up to 322 tbps of capacity for CRS-3 more than tripling the 92 tbps capacity of the Cisco CRS-1. CRS brings industry-leading efficiency, power saving, cooling and rack installation creativity, with bandwidth up to a variety of services.

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.

CRS-3 offers many advantages

• Powered by QuantumFlow Array, one of the world’s most sophisticated chipset architectures, which includes a 140-Gbps application-specific integrated circuit (ASIC) based on 65-nanometer (nm) technology; QuantumFlow Array was engineered for the Cisco CRS Family of routers to provide higher bandwidth without compromising service performance
• Supported across all the Cisco CRS-1 and CRS-3 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 an 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 discrete ingress and egress packet handling
• Single-flow traffic processing at 140 Gbps in each direction
• Enhanced onboard multi-core CPU for accelerated software processing
• Optimized for label switching functions in a service provider’s network
• Packet Transport forwarding engine with industry-leading, wire-rate performance at 140 Gbps
• Additional services such as class of service (CoS) processing, multicast, traffic engineering, and statistics gathering, all performed at line-rate 140 Gbps
• Support for up to 8 queues per port
• Scale for hundreds of thousands of LSPs and traffic engineering midpoints
• Built-in support for carrier-class high availability with fast reroute (FRR) capability, providing guaranteed restoration in 50 ms in case of link and node failures
• Built-in hardware acceleration for critical network control traffic
• Built-in support for video monitoring for a comprehensive video quality of experience (QoE)
• Accurate hardware-assisted time-stamping support for service-level agreement (SLA) monitoring
• Industry-leading environmental efficiency with a lower power and weight profile
