Abstract

This paper proposes a scheme for implementing multiparty videoconferencing service on SONET/ATM rings. Different multicasting methods on SONET/ATM rings are discussed and compared. A new multicast VP called" Multi-drop VP" which is particularly suitable for SONET/ATM rings is proposed. An Add-Drop Multiplexer(ADM) structure for rings capable of multi-dropping is also presented. Several VP assignment schemes are proposed and their bandwidth utilizations are compared.
