Internetworking data services

This paper describes considerations for potential future public data communication services interconnecting users on private local area networks belonging to different administrative domains. The relevant management issues are addressed in an architecture consisting of distributed software modules organized in a hierarchical structure supporting network administration functions. The authors describe an experimental internetworking unit being built to explore the functional capabilities needed to interface ethernet networks to systems operating at OC-3 SONET/SDH rates of 155.22 Mb/s with basic asynchronous transfer mode (ATM) transport capabilities. They describe bandwidth allocation, address screening, address translation, and traffic monitoring service aspects in the experimental prototype
