Data Sheet

Cisco CRS 8-Slot Single-Shelf System

The Cisco

Carrier Routing System (CRS) offers industry-leading performance,

advanced services intelligence, environmentally conscious design, and system
longevity. The Cisco CRS is powered by 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 interactive multimedia transported on the

Next-Generation Network (NGN) in multiple directions. This new traffic strains the architectural foundations of both

public and private networks serving businesses and consumers. As part of a media-aware Cisco Next Generation

Network, the Cisco CRS delivers highly reliable operations and scales easily from single-chassis form factors to a

massive multi-chassis system. The Cisco CRS also referred to as the CRS-1, CRS-3, and CRS-X is a system that

is both forward and backward compatible, built for investment protection and designed to provide industry-leading

efficiencies in scaling, energy use, cooling, and rack-space resources.

The Cisco CRS 8-Slot Single-Shelf System (Figure 1) offers many advantages:

●

The system is powered by a chipset architecture engineered for the Cisco CRS Router Family, which

provides higher bandwidth than competing products, without compromising service performance. The Cisco

CRS chipset is based on multidimensional engineering that includes several functional components working

in tandem throughout the platform.

●

The system uses Cisco IOS XR Software, the only fully modular, fully distributed internetwork operating

system using a memory-protected, microkernel-based architecture and control-plane distribution that allows

the system to scale and provide always-on operation.

●

This single-shelf system is compatible with existing and future line cards of the Cisco CRS Family.

●

The fully redundant carrier-class configuration supports in-service upgrades from 40 Gbps to 400 Gbps per

slot.

●

Integrated technology includes IP and Multiprotocol Label Switching (MPLS) routing, IP over dense

wavelength-division multiplexing (IPoDWDM), network virtualization with secure domain routers (SDRs),

fabric multicast replication, fabric quality of service (QoS), Cisco NetFlow accounting, and Carrier-Grade

IPv6 (CGv6) to provide an outstanding quality of experience (QoE) at the lowest possible total cost of

ownership (TCO).

●

The system can also scale with back-to-back system capability, connecting two CRS 8-Slot Chassis

directly, using switch fabric cards and optical cables to form a single logical system.
