The Cisco ASR 1000 Series Embedded Service Processors (ESPs) are based on the innovative, industry-leading Cisco QuantumFlow Processor for next-generation forwarding and queuing in silicon. These modules use the first generation of the hardware and software of the Cisco QuantumFlow Processor architecture.

The 5-, 10-, 10-N-, 20-, and 40-Gbps Cisco ASR 1000 Series ESPs (part numbers ASR1000-ESP5, ASR1000-ESP10, ASR1000-ESP10-N, ASR1000-ESP20, and ASR1000-ESP40, respectively) provide five centralized forwarding-engine options for the Cisco ASR 1000 Series Aggregation Services Routers. Additionally, the Cisco ASR 1002 Fixed Router includes a nonmodular, fixed ESP with throughput of 2.5 Gbps and the Cisco ASR 1001 Router comes with a nonmodular, fixed ESP with throughput of 2.5 Gbps, upgradable with a software-activated performance upgrade license to 5 Gbps.
