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 four different versions: the Cisco ASR 1002-Fixed
Router, the Cisco ASR 1002 Router, the Cisco ASR 1004 Router, and the Cisco ASR
1006 Router. All four 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 Cisco Unified Border Element (CUBE) for Enterprise 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-F, 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.
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-F, 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
