The ASR9000[1] is a router built by Cisco Systems, intended for the Service Provider market.

Its major characteristics are:

  • Designed for Metro Ethernet networks
  • Designed for video and other high bandwidth applications
  • Supports a variety of interface types, those commonly used by Service Providers
  • Uses IOS-XR, a full-featured OS

History[edit]

Networking equipment was traditionally categorized as either a Switch 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 Service Provider, and vice-versa.

Prior to the ASR9000, Cisco's high-end SP product portfolio consisted of the CRS-1, the GSR, and the 7600 (and the 6500). The ASR9000 is the successor to both the GSR and the 7600. When the CRS-1 is deployed in a large network at the core, the ASR9000 complements it on the edge; both run IOS-XR. In 2011, Cisco announced capacity upgrades and support of network Virtualization (nV) capabilities[2] for the ASR9000. In 2011, the ASR9000 was awarded "Best Carrier Ethernet Aggregation Product" at the Carrier Ethernet World Congress.[3]
