Cisco CRS-3 Label Switch Processor

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, an

exceptional self-healing, distributed operating system.

Data-based communications are being replaced by video and interactive media traversing the IP Next-Generation

Network (IP NGN) in multiple directions, straining the architectural foundations of both public and private networks

that serve 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 multichassis system. Its highly efficient design conserves power, cooling, and rack-space resources while

optimizing bandwidth capacity. The Cisco CRS-3 is compatible with the Cisco CRS-1 Carrier Routing System,

protecting investments for decades to come.

Product Overview

The Cisco CRS-3 Label Switch Processor provides 140-Gbps distributed forwarding engine capability for the Cisco

CRS Family. The label switch processor allows a Flexible Packet Transport solution and is responsible for

forwarding processing tasks, handling all network traffic flows through the data plane. Distinctive features of the

label switch processor include the ability to switch Multiprotocol Label Switching (MPLS) traffic at high throughput

and low latency and jitter, immediate scalability to hundreds of thousands of Label Switched Paths (LSPs).
