The Cisco CRS-1 carrier routing system is the industry's first carrier router offering continuous system operation, unprecedented service flexibility, and system longevity. The Cisco CRS-1 is powered by Cisco IOS XR software - a unique self-healing, distributed operating system designed for always-on operation while scaling system capacity. The system architecture combines the Cisco silicon packet processor, the first programmable 40-Gbps application-specific integrated circuit (ASIC), with the Cisco service separation architecture for unprecedented service flexibility and speed to service. The Cisco CRS-1 marks the era in carrier IP communications by powering the foundation for network and service convergence today while protecting investments for decades to come.
