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.
