Proactive Approach to Reconstructing Degree-constrained Application Layer Multicast Tree

In Application Layer Multicast(ALM), if none-leaf nodes leave or fail, all of this node's download nodes will be greatly affected.On this issue, this paper proposes a new proactive approach to restore overlay multicast, and each non-leaf node precalculates a parent-to-be for each of its children.So that the non-leaf node fails or leaves, the children nodes can accept data quickly from parent-to-be.Simulation experiment demonstrates the proactive approach can recover from node departures about 3 times faster than reactive approach, and average delivery delay is smaller than other proactive approaches with low overheads.
