ASR 1000 Series Embedded Services
Processors (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 (Figure 1). The 5-Gbps
ESP (ESP5) supports 5 Gbps of bandwidth. The 10-Gbps ESP (ESP10 and ESP10-N)
support 10 Gbps of bandwidth and can be deployed in customer networks that require
1+1 redundancy. The 20-Gbps ESP (ESP20) supports 20 Gbps of bandwidth and can be
deployed in customer networks that require 1+1 redundancy (refer to fault-tolerant
configuration in Table 3).
Performance highlights of the ESP20 include hardware-assisted quality of service (QoS),
encryption capability of 8 Gbps, and special jitter- and latency-minimizing multicast packet
replication. Encryption capability of the ESP10 is rated for 4 Gbps whereas ESP5 is rated for 1.8
Gbps. The ASR1000-ESP10-N has the same performance characteristics as the ASR1000-ESP10
but does not support encryption services.
All three ESPs are based on the innovative Cisco Packet Processor for next-generation forwarding
and queuing in silicon.
