Improved reconstruction scheme for application multicast tree.
Shunyi Zhang · Computer Engineering and Applications Journal · 2008
Proactive scheme have a shorter recovering time than reactive approach.In this paper a modified delay and degree-constrained scheme named DDCP is proposed.Compared with previous one,the new approach ensures the delay requirement is satisfied while the degree constraint is not violated.At the same time a degree pre-reserved initial tree-construction algorithm is also put forward to improve the efficiency of DDCP.Whatever the responsiveness of the recovery process,the quality of the restored tree or the recovery overhead DDCP have improved to some extent.Simulation tests proved it.
