The Cisco® ASR 1000 Series Embedded Service Processors (ESPs) are based on the innovative, industry-leading Cisco QuantumFlow Processor for next-generation forwarding and queuing in silicon. These modules use the first generation of the hardware and software architecture known as Cisco QuantumFlow Processor.
The 5-, 10-, 10-N-, and 20-Gbps Cisco ASR 1000 Series ESPs (part numbers ASR1000-ESP5, ASR1000-ESP10, ASR1000-ESP10-N, and ASR1000-ESP20, respectively) provide four centralized forwarding-engine options for the Cisco ASR 1000 Series Aggregation Services Routers. Additionally, the ASR 1002-Fixed includes a non-modular, fixed ESP with throughput of 2.5-Gbps.
The Cisco ASR1000-ESP10-N is the nonencryption version of the ASR1000-ESP10. The ASR1000-ESP10-N can only support noncrypto Cisco IOS® Software images and will never support encryption capabilities such as IPSec. In future releases, the ASR1000-ESP10-N may support secured network management features such as SSH, SSL, and SNMPv3.
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 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. They are also responsible for features such as firewalls, intrusion prevention, Network Based Application Recognition (NBAR), Network Address Translation (NAT), and flexible pattern matching.
The Cisco ASR 1002-Fixed is the only chassis that supports the 2.5-Gbps ESP, which is integrated in the chassis. The 5-Gbps Cisco ASR 1000 Series ESP (ASR1000-ESP5) supports 5-Gbps bandwidth and is supported exclusively in combination with the Cisco ASR1002 Router chassis. The 10-Gbps Cisco ASR 1000 Series ESP (ASR1000-ESP10 and ASR1000-ESP10-N; Figure 1) supports 10-Gbps bandwidth, is supported on all Cisco ASR 1000 Series chassis, and can optionally be deployed in customer networks that require 1+1 redundancy.1 The 20-Gbps Cisco ASR 1000 Series ESP (ASR1000-ESP20) supports 20-Gbps bandwidth, is supported on the Cisco ASR 1004 and ASR 1006 Router chassis, and can optionally be deployed in customer networks that require 1+1 redundancy.
Performance highlights of the 20-Gbps ESP include hardware-assisted policing, encryption capability of 8 Gbps, and special jitter- and latency-minimizing multicast packet replication. The encryption capability of the 10-Gbps ESP is rated for 4 Gbps whereas the 5-Gbps ESP is rated for 1.8 Gbps and the 2.5-Gbps ESP is rated for 1.0 Gbps. The ASR1000-ESP10-N has the same performance characteristics as the ASR1000-ESP10 but does not support encryption services.
