The Cisco® CRS Carrier Routing System 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 rich media transported on Next-Generation Networks (NGN) in multiple directions. The new traffic strains the architectural foundations of both public and private networks serving businesses and consumers. As part of the medianet, a media-aware Cisco IP NGN, the Cisco CRS delivers highly reliable operations and scales easily from numerous single-chassis form factors to a massive multi-chassis system. Its design provides industry-leading, efficiency, with very low consumption of power, cooling and rack-space resources, while providing intelligent service-rich bandwidth capacity. The Cisco CRS is backward and forward compatible, protecting existing and future investments for decades to come.

Figure 1. Cisco CRS 4-Slot Single-Shelf System

The Cisco CRS 4-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 that uses a memory-protected, microkernel-based architecture and control-plane distribution, allowing the system to scale.

The Cisco CRS 4-Slot Single-Shelf System offers a fully redundant carrier-class configuration.

Integrated technology includes IP/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 outstanding quality of experience (QoE) at the lowest total cost of ownership (TCO).
