What is ISR?
ISR–Integrated Service Routers, generally used as internet edge for customers with small/medium networks.
But what’s Integrated Service? Wikipedia’s explanation is to say integrated services is an architecture that specifies the elements to guarantee the quality of service (QoS) on networks. IntServ can, for example, be used to allow video and sound to reach the receiver without interruption.
What is ASR?
ASR–Aggregation Services Routers, generally used as internet edge for enterprise networks and service providers.
Currently, Cisco ISR Routers include 800 Series ISR, 1900 Series ISR, 2900 Series ISR, 3900 Series ISR, 4000 Series ISR, etc. And the Cisco ASR Routers consist of 900 Series ASR, 1000 Series ASR, 5000 Series ASR, 9000 Series ASR, etc.
