History

In the past, networking equipment was categorized as either a Switch

 traffic. As products became more sophisticated, the distinction between a switch and a router became blurred, as high-end switches were being designed to, in addition to bridging, to route traffic as well, and likewise routers were being designed to do L2 switching also. At the same time, it was becoming clear that the needs for the Enterprise market were diverging from those of the Service Provider market. Though still maintaining the terms Switch and Routers in their product names, Cisco divided their high-end networking products into those aimed for the Enterprise market and those aimed for the Service Provider market. In reality, many Enterprise customers use equipment Cisco categorizes under the banner of Service Provider, and vice-versa.

Prior to the introduction of the ASR9k, Cisco's high-end SP product portfolio consisted of the CRS-1, the GSR

). The ASR9k fits well within this product portfolio; it is the logical successor to the GSR and the 7600. When the CRS-1 is deployed in a large network at the core, the ASR9k complements it on the edge; both run IOS-XR. In 2011 Cisco announced capacity upgrades and support of innovative new network Virtualization (nV) capability for the ASR9000. In 2011 the ASR9K was awarded "Best Carrier Ethernet Aggregation Product" at the Carrier Ethernet World Congress
