In online multicast sessions, multicast group members join and leave the multicast session frequently. When real-time communications is concerned, online multicast routing becomes tougher. Real-time communications imposes its additional constraints, such as end-to-end delay, to multicast routing. Rigid delay constraints of real-time communications restrict computational effort for online update of multicast trees.In this thesis, two online multicast routing heuristics and one unicast routing heuristic is proposed for real-time communications. Performance of proposed heuristics is evaluated using online and offline multicast routing heuristics from literature. Simulations indicate that our heuristics offer the best balance among performance and computational effort.
