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 through 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 control
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 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 processing-based forwarding engine and
other system components.

ASR 1002 Router must not be opened. If there
is a problem with eUSB flash card, the chassis
should be returned.
