Protocols for ATM access networks

The development and standardization of ATM (asynchronous transfer mode) and signaling protocols for BISDN (broadband integrated services digital network) are considered. A view of both ATM and signaling protocols in which the key design guideline is service flexibility is presented. The approaches suggested are intended to create a service-independent broadband facility that is also sensitive to both service performance and network efficiency. Key issues are raised that will require serious consideration by standards groups, manufacturers, and service providers as BISDN moves toward production.<>
