This paper describes how Networking BroadBand Services (NBBS) provides
multiple protocol support over emerging high-bandwidth networks. It d
escribes the problems associated with handling these multiple protocol
s that are seen now more than ever in the emerging asynchronous transf
er 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 i
s given to provide the reader with a feeling for typical access servic
es issues. Brief examples of access services are given to show how the
concepts described are being used.
