Cisco Carrier Routing System Chassis:

• CRS-3
• CRS-1

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 a unique self-healing distributed operating system.

Packet-based data communications are being replaced by video and rich media traversing the IP Next-Generation Network (NGN) in multiple directions straining 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-3 delivers continuous always-on operations and scales easily from numerous single-chassis form factors to a massive multi-chassis system. Its design provides an industry-leading efficiency consuming lowest power cooling and rack-space resources for an intelligent service-rich bandwidth capacity. The CRS-3 builds on the CRS-1 being backward and forward compatible protecting existing and future investments for decades to come.
