Overlay multicast scheme has been regarded as an alternative to conventional IP multicast since it can support multicast functions without infrastructural level changes. However, multicast tree reconstruction procedure is required when a non-leaf node fails or leaves. In this paper, we propose a proactive approach to solve the aforementioned defect of overlay multicast scheme by using a resource reservation of some nodes’ out-degrees in the tree construction procedure. In our proposal, a proactive route maintenance approach makes it possible to shorten recovery time from parent node’s abrupt failure. The simulation results show that proposed approach takes less time than the existing works to reconstruct a similar tree and that it is a more effective way to deal with more nodes that have lost their parent nodes due to failure.
