Data Sheet

Cisco CRS 16-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 numerous single-chassis form

factors to a massive multichassis 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, while providing intelligent

and comprehensive service bandwidth capacity.

The Cisco CRS 16-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, designed for always-on operation. Cisco IOS XR Software is 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.

●

This single-shelf system is fully compatible with existing and future components of the Cisco CRS Family,

such as router processors and line cards.

●

The fully redundant carrier-class configuration supports in-service upgrades from 40 Gbps per slot and 140

Gbps per slot to 400 Gbps per slot, when available, and from a single-chassis to a multichassis system.

●

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 Cisco CRS 16-Slot Chassis

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