® 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 up to 92 Tbps. The innovative 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 a new era in carrier IP communications by powering the foundation for network and service convergence today while protecting investments for decades to come.
This data sheet provides detailed product specifications for the Cisco CRS-1 16-Slot Line Card Chassis Route Processor (Figure 1). The Cisco CRS 16-Slot system supports two route processors for control plane redundancy. The Cisco CRS-1 16-Slot Line Card Chassis Route Processor B comes with a dual 1.2-GHz CPU symmetric multiprocessing (SMP) complex that controls and powers this multiterabit router. The route processor controls all shelf management functions and runs the routing protocols suite powered by Cisco IOS-XR Software designed for carrier-class networks.
