Cisco ASR 9000 Series Route Switch Processor (RSP) is a scalable, low-power, carrier Ethernet platform with a system architecture specifically designed to accommodate service providers' unique convergence requirements of Layer 2 Ethernet transport plus Layer 3 services.

The Cisco ASR 9000 Series Route Switch Processor (RSP) is designed to deliver the high scalability, performance, and fast convergence required for demanding video, cloud, and mobile services.

Highly scalable fabric
It is designed to support high 1/10/100-Gbps port densities and provides built-in scalability for investment protection.

Dual RSP to provide an active-active switch fabric
It offers traffic load balancing simultaneously across both fabrics and offers highly available system where loss of one RSP allows for unimpeded performance per slot.

Distributed forwarding plane architecture
It allows line cards to support independent forwarding for enhanced performance and scale.

Virtual output queuing and arbitration
It offers service intelligence with prioritization of traffic and provides efficient congestion management mechanism and avoids problems related to head-of-line blocking.

Centralized arbiter
It uses an efficient credit mechanism to help ensure transparent switchover with zero packet loss.

Front-panel LEDs
It provides visual indication of RSP status, power management, and activity on compact flash and HDD.
