Cisco ASR 1000 Series

Cisco ASR 1000 Series Routers transform and future-proof the network edge for
service providers and enterprises by offering industry-leading performance,
service capabilities, reliability, and efficiencies in a compact form factor. The Cisco
ASR 1000 Series consists of three different versions: the Cisco ASR 1002 Router,
the Cisco ASR 1004 Router, and the Cisco ASR 1006 Router. All three models use
the powerful Cisco QuantumFlow Processor which provides a leap in performance
and resiliency for network processors.
The Cisco ASR 1000 Series delivers multiple services embedded in the Cisco
QuantumFlow Processor at wire speeds of up to 20 Gbps. The services supported
on the Cisco Packet QuantumFlow Processor include security services (for example,
encryption and firewall), Quality of Service (QoS), Network Based Application
Recognition (NBAR), Cisco IOS ® Flexible Packet Matching, broadband aggregation,
and session border controller, among others.
With the separation of the control and data planes in the Cisco ASR 1000 Series
Router architecture, software redundancy (on the Cisco ASR 1002 and 1004
models) and hardware redundancy (on the Cisco ASR 1006 Router) are provided.
Additionally, the modular Cisco IOS XE Software that is introduced with the Cisco
ASR 1000 Series facilitates In Service Software Upgrade (ISSU).
The Cisco ASR 1000 Series is supported in Cisco IOS XE Software, which is
introduced with the Cisco ASR 1000 Series Routers as a modular operating system.
Based on Cisco IOS Software Release 12.2SR, Cisco IOS XE Software is designed to
provide modular packaging, feature velocity, and powerful resiliency. Because of the
extreme flexibility and robust performance of the Cisco ASR 1000 Series Embedded
Services Processors (ESPs), which are based on the Cisco QuantumFlow Processor
technology, Network Security, Deep Packet Inspection, Cisco IOS Firewall, and many
other advanced features are implemented in Cisco IOS XE Software without the
need of additional hardware support (for example, in the form of a service blade).
One of the most innovative features is that the Cisco IOS XE Software supports
dual Cisco IOS Software images in one single Cisco ASR 1000 Series Route
Processor for software redundancy in the Cisco ASR 1002 and the Cisco ASR 1004
Router. This dual Cisco IOS Software image could be the same image for backup,
or a different image also on a different Cisco IOS XE Software release for resilient
upgrade. Information about the compatibility of supported dual images is available in
