The Cisco ASR 1000 Series Embedded Service Processors (ESPs) are based on the innovative, industry-leading Cisco Quantum Flow Processor for next-generation forwarding & queuing in silicon. These modules use the first generation of the hardware & software architecture known as Cisco Quantum Flow Processor. The Cisco ASR 1000 Series ESPs are responsible for the data-plane processing tasks, & all network traffic flows through them. The modules perform all baseline packet routing operations, including MAC classification, layer 2 & layer 3 forwarding, quality-of-service (Qo S) classification, policing & shaping, security access control lists (ACLs), VPNs, load balancing, & Net Flow. They are also responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), & flexible pattern matching. The 5-Gbps Cisco ASR 1000 Series ESP (ASR1000-ESP5) supports 5-Gbps bandwidth & is supported exclusively in combination with the Cisco ASR1002 Router chassis.
