TheCisco Aggregation Services Router (ASR) series of routers are modular routers produced byCisco Systems. The highest end of the lineup, the ASR 9000 series, is intended forservice provider (SP) core networks.
Networking equipment was traditionally categorized by functionality as being either aswitch or a router. Switches bridged (transmitted) L2/Ethernet traffic, and a router forwarded (transmitted and routed) L3/IP traffic. As products became more sophisticated, the distinction between a switch and a router became blurred as high-end switches began to route traffic in addition to bridging, and likewise routers began to perform L2 switching. At the same time, the enterprise market was diverging from the service provider market. Though still maintaining the terms switch and router in their product names, Cisco divided their high-end networking products by market. However, many enterprise customers chose equipment Cisco categorized under the banner of being intended for service providers, and vice versa.
Prior to the ASR 9000 series, Cisco's high-end SP product portfolio consisted of theCRS-1, theGSR, and the7600 (and the6500). The ASR 9000 series devices are the successor to both the GSR and the 7600. When the CRS-1 is deployed in a large network at the core, the ASR 9000 complements it on the edge; both run IOS-XR. In 2011, Cisco announced capacity upgrades and support of network Virtualization (nV) capabilities[1] for the ASR 9000. In 2011, the ASR 9000 was awarded "Best Carrier Ethernet Aggregation Product" at the Carrier Ethernet World Congress.[2]
The ASR 900 series is a chassis-based modular router that runs theCisco IOS XE Linux-based operating system.[3]
The ASR 920 series is a chassis-based modular router running Cisco IOS XE.[4]
The ASR 1000 series is chassis-based modular router running Cisco IOS XE.[5]
Cisco ASR 9000 series routers arerouters designed for the service provider market. It runs theIOS XR Linux-based operating system.[6]
