Access services for the Networking BroadBand Services architecture

This paper describes how Networking BroadBand Services (NBBS) provides multiple protocol support over emerging high-bandwidth networks. It describes the problems associated with handling these multiple protocols that are seen now more than ever in the emerging asynchronous transfer mode (ATM) infrastructure. The paper addresses the access services of NBBS and how the NBBS transport functions are used to provide these access services. A detailed example of one access service component is given to provide the reader with a feeling for typical access services issues. Brief examples of access services are given to show how the concepts described are being used.
