Multiparty videoconferencing on multi-drop VP-based SONET/ATM rings: performance analysis
Gang Feng, T.-S.P. Yum · IEE Proceedings - Communications · 1998
A type of multiparty videoconferencing in VP-based SONET/ATM ring networks under the minimum hop routing rule is analysed. For this type of conference, only the video and voice of the current speaker are broadcast to other conferees. A queueing model is presented. Conference blocking probabilities and video freeze probabilities are derived and are shown to be in close agreement with the simulation results.
