Description
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. The 10Gbps Cisco ASR 1000 Series ESP is responsible for data-plane processing tasks, and all network traffic flows through it. It performs all baseline packet routing operations, including MAC classification, Layer 2 and Layer 3 forwarding, QoS classification, policing and shaping, security access control lists (ACLs), VPNs, load balancing, and NetFlow. It is also responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), and flexible pattern matching.
