CONNECTION OPTIMIZATION FOR 2 TYPES OF VIDEOCONFERENCE

The connection optimisation problem for two types of multipoint videoc onferences is formulated. The first type is called a selectable media conference. In this type each conferee can choose to receive a particu lar video composition. In the second type, called a common media confe rence, only one composite video is generated for all conferees in this type of conference. Algorithms that use a combination of look-up tabl e and online processing are designed for computation of the optimal pa ths for connecting the conference sites. The blocking probabilities fo r these two types of videoconference in fully connected networks are d erived and compared. The sensitivity of network throughput to conferen ce-size distribution is also studied.
