A Survey of Routing Algorithms and Protocols in Overlay Multicast
Wu Jia · 2007
Though the performance advantage of IP multicast is undeniable, the deployment of IP multicast has met many difficulties. In recent years, overlay multicast is being increasingly recognized as a viable alternative. In this paper, an overview of overlay multicast routing algorithms and protocols were provided. A general overlay multicast network model was proposed, and the routing optimal problems in overlay multicast were identified and classified. Based on above work, some recent important overlay multicast routing algorithms and protocols were described, and a set of properties of them, including performance metric, routing problem solved, system structure and control method etc., were fully analyzed and discussed. In addition, some further research problems in overlay multicast routing were also pointed out.
