Networks are facing new challenges with the Internet of Everything. Trillions of things have become Internet ready
and can start talking to each other, as well as to applications and people. The effects of machine-driven events
change network dynamics and impose entirely new service requirements. Managing bandwidth is no longer
enough. Networks must become more elastic and programmable, capable of adapting and evolving. As part of an
evolving and programmable network, the Cisco CRS delivers highly reliable operations and scales easily from
single-chassis form factors to a massive multichassis system. Its design offers industry-leading efficiency in power
consumption, cooling, and rack-space resources, while providing intelligent service-rich bandwidth capacity. The
Cisco CRS supports up to 400-Gbps line rates, and its hardware is backward and forward compatible, helping to
protect existing and future investments.
Product Overview
Cisco CRS label switch processors provide distributed forwarding-engine capability for the Cisco CRS platform.
The label switch processors allow a flexible packet transport solution and are responsible for forwarding-processing
tasks, handling all network traffic flows through the data plane. They can switch Multiprotocol Label Switching
(MPLS) traffic at high throughput and low latency and jitter and offer immediate scalability to hundreds of
thousands of label switched paths (LSPs).
Both the Cisco CRS-X Label Switch Processor and the Cisco CRS-3 Label Switch Processor are supported across
the Cisco CRS 8-slot, 16-slot, and multichassis form factors and are compatible with both Cisco CRS enhanced
chassis and legacy chassis-based systems.
The Cisco CRS-X Label Switch Processor (Figure 1) features two 200-Gbps forwarding ASICs and can operate in
either 200-Gbps or 400-Gbps mode. While operating in a 400-Gbps mode in a Cisco CRS enhanced chassis-
based system, the line card delivers full 400-Gbps line-rate throughput. In a 200-Gbps mode, one of the two
forwarding ASICs is in a shut-down state to conserve on power and thermals.
