The Cisco ASR1000-ESP20 forwarding performance will vary depending on features configured. Up to 4 Mpps for the combination of the following commonly-used features: IPv4 forwarding, IP Multicast, ACL, QoS, Reverse Path Forwarding (RPF), load balancing, and Sampled NetFlow.
This ASR1000-ESP20 is similar with the ASR1000-ESP20=. The ASR1000-ESP20= is a spare one.
Figure 1 shows the appearance ofASR1000-ESP20.
The Cisco ASR 1000 Series embedded service processors:
(1)Provide the centralized embedded forwarding services responsible for the bulk of the data plane processing tasks. All network traffic through the Cisco ASR 1000 Series system flows through the Cisco ASR 1000 Series Embedded Services Processors.
(2)Are responsible for the data-plane processing tasks and all network traffic flows through them.
(3)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.
(4)Support Cisco QuantumFlow Processor (QFP) forwarding engines.
(5)Support QFP provisioned with two TCAM4 devices for ACL lookup and other software features.
(6)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, NetFlow.
(7)Are responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), and flexible pattern matching.
(8)Incorporates a security encryption coprocessor to assist encryption processing common to all embedded services processors. The security processor operates in coprocessor mode and only processes packets sent to it by the Cisco QFP.
(9)Provide hardware abstraction layer between the packet processing-based forwarding engine and other system components.
