ISR G2 is a second generation Integrated Services Router (ISR) from Cisco Systems, Inc.
According to Cisco, ISR G2 routers are built to accommodate the need for branch offices to use video-conferencing and virtualization services and transport other kinds of rich media over a wide area network (WAN). The new features in Cisco ISR G2 include video streaming and on-demand services support. Deployment and maintenance processes have been simplified, and network performance and energy management improved over the previous generation of routers.
Cisco Integrated Service Routers Generation 2 (ISR G2) improve on Cisco's range of "branch office routers" by integrating multiple network services into a single platform and providing services that previously required additional hardware to run.
Cisco ISR G2 was launched in 2009 and is part of the Cisco Borderless Network Architecture system.
