Realizing a multimedia broadband integrated network

Recent advances in fiber optics and data compression technologies have resulted in the realization of very high-speed communication networks. These networks are being designed to carry a wide variety of traffic types including voice, video and multimedia data. This paper discusses the many challenges and issues involved in realizing a broadband multimedia network. A possible scenario of ATM-based B-ISDN is given. The design of a new transmission scheduling mechanism that not only guarantees QOS requirements for the different traffic classes, but can also transport bursts of sessions as a whole, thereby preserving integrity of user talkspurt in a bursty traffic environment, is presented. Simulation results demonstrate the feasibility of the scheme.
