An implementation of a residential gateway controller for a fixed bandwidth-sharing multiservices residential access network

As access technologies evolve, multiple services residential gateways are providing more and more integrated services to customer premises equipment. However, shared residential bandwidth does not guarantee quality of service. The paper presents our design of a fixed bandwidth-sharing multiple services access network, which is based on SONET/SDH over DWDM technology. This design allocates fixed bandwidth to each access point to guarantee quality for high bandwidth demanding services. Since system stability and low cost of the residential gateway are crucial to subscribers, we mainly focus on single chip implementations. One of our implementations, an implementation of the fixed bandwidth-sharing multiservices protocol on the Altera 10KE series PLD, is presented. It demonstrates the integrated services of two 10BaseT Ethernet connections and two 64 Kbps digital phone channels.
