Chapter 2 Cisco ASR 1000 Series Routers Components
Cisco ASR 1000 Series Embedded Services Processor
The Cisco ASR 1000 Series Embedded Service Processors, Cisco ASR 1000-ESP5 and Cisco
ASR1000-ESP10 provide two centralized forwarding-engine options for the Cisco ASR 1000 Series
Aggregation Services Routers. The Cisco ASR 1000 Series ESPs:
•Are responsible for the data-plane processing tasks and all network traffic flows through them.
•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.
The 5-Gbps Cisco ASR 1000 Series ESP (ASR1000-ESP5) supports 5-Gbps bandwidth and is supported
only on the Cisco ASR1002 Router chassis. The 10-Gbps Cisco ASR 1000 Series ESP supports 10-Gbps
bandwidth, is supported on all Cisco ASR 1000 Series chassis.
The Cisco ASR 1000 Series Routers support the following ESPs:
•Cisco ASR 1000 Series ESP10—Supports forwarding performance with up to 8 Mpps with baseline
features and bandwidth of 10Gbps. The Cisco ESP10 is located in:
–
Cisco ASR 1006 Router physical slots 3 and 4 and are labeled F0 and F1.
–
Cisco ASR 1004 Router physical slot 1 and is labeled F0.
–
Cisco ASR 1002 (which can use either the ESP10 or the ESP5; but Cisco ASR 1002 Router is
the only chassis that supports Cisco ASR1000-ESP5)
•Cisco ASR 1000 Series ESP5—Supports forwarding performance with up to 4 Mpps with baseline
features and bandwidth of 5Gbps. The Cisco ASR1000-ESP5 is in slot 1 and is labeled F0 in the
Cisco ASR 1002 Router.
The Cisco ASR 1000 Series Embedded Services Processor consists of three main elements:
•Embedded services processor for packet processing and queueing and scheduling
•Data plane interconnect
•Forwarding Engine Control Processor (FECP) (located on the Cisco ASR Series Embedded Services
Processor)
The forwarding processors for all initial Cisco ASR 1000 Series Embedded Services Processors are
based on a common highly-programmable network Cisco QuantumFlow Processor (packet processing).
The Cisco ASR 1000 Series Embedded Services Processor (ESP) consists of a front panel label for
indicator and control functions. The Cisco ASR 1000 Series Embedded Services Processor model
number labeling is located on the left card module handle. The module also contains card handles to
assist in insertion or removal of the module.
