The Cisco ASR 1000 Series Embedded Service Processors
(ESPs) are based on an innovative new Cisco processor for next-generation forwarding
and queuing in silicon. The Cisco ASR 1000 Series ESP 10 Gbps is supported
on the Cisco ASR 1004 and 1006 Routers. On the Cisco ASR 1006 Router, it can
be deployed in a redundant configuration.
The Cisco ASR 1000 Series ESPs are responsible for
the data-plane processing tasks and all network traffic flows through them.
The modules perform all baseline router packet operations, including:
MAC classification
Quality-of-service (QoS) classification, policing, and shaping
Security
access control lists (ACLs)
VPNs
Load balancing
NetFlow
They are also responsible for advanced services such
