Abstract :
To ensure the quality of a multimedia teleconference, it is essential that sufficient bandwidth be allocated for its use. In this paper a conference traffic model is formulated and link level and conference level congestion measures are derived. Motivated by the advantages of sharing transmission resources in TASI related voice communication systems, an analogous transmission policy for conference videos is proposed. The quantification of conference traffic also enables us to set an admission policy so that the network can accommodate as many conferences as possible without violating conference quality constraints.<>
