Cisco ASR 1000 Series Embedded Services Processors

The Cisco ASR 1000 Series Embedded Services Processor (ESP) is based on the Cisco QuantumFlow

Processor for next-generation forwarding and queuing.

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 thro ugh the

Cisco ASR 1000 Series Embedded Services Processors.

• Are responsible for the data-plane processing tasks and all network traffic flows through them.

• Support Forwarding Engine Control Processor which provide hardware abstraction layer between

the QFP-based forwarding engine and other system components, allowing datapath and management

functions to be independent.

• 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, quality-of-service (QoS) classification, policing and shaping, security access cont rol

lists (ACLs), VPNs, load balancing, and NetFlow.

• 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 processin g 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 processing- based forwarding engine and

other system components.

1FO slot 3The eUSB panel door on the side of the Cisco

ASR 1002 Router must not be opened. If there

is a problem with eUSB flash card, the chassis

should be returned.
