Cisco ASR 1000 Series Embedded Services Processors
The Cisco ASR 1000 Series Embedded Services Processor (ESP) is based on the Cisco QuantumFlow Processor for
The Cisco ASR 1000 Series ESPs:
•Provide the centralized embedded forwarding services responsible for the bulk of the data plane processing tasks. All network traffic through the Cisco ASR1000 Series system flows through the Cisco ASR 1000 Series Embedded Services Processors.
•Are responsible for the
•Support Forwarding Engine Control Processor which provide hardware abstraction layer between the
•Support Cisco QuantumFlow Processor (QFP) forwarding engines.
•Support QFP provisioned with two TCAM4 devices for ACL lookup and other software features.
•Perform all baseline packet routing operations, including MAC classification, Layer 2 and Layer 3 forwarding,
•Are responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), and flexible pattern matching.
•Incorporates a security encryption coprocessor to assist encryption processing common to all ESPs. The security processor operates in coprocessor mode and only processes packets sent to it by the Cisco QFP.
•Provide hardware abstraction layer between the packet
