Design of broadband controller for residential gateway applications

As Internet technology becomes more pervasive, homes are getting connected to cable or DSL. The increasing user demands for "always on" service along with multiple connectivity for voice and data is gradually making the presence of a residential gateway in every household a reality. A residential gateway should have routing and bridging capabilities along with seamless connectivity to contemporary premise networking technologies. Integration of all these features on a single device essentially requires a rich architecture, smart design techniques and thorough verification. This paper describes the architecture and design of a broadband network controller which is a critical component of TI's voice and data centric residential gateway solution.
