Study of Application-Layer Multicast Based on Hierarchy
FU Xiao-qing · Journal of Dalian Jiaotong University · 2009
A P2P network application layer multicast tree is studied in the sharing mechanism,and a hierarchical structure is proposed based on the application layer multicast program.The model consists of the points from the upper and lower levels of logic on the middle and lower levels of resources by the network nodes with the upper nodes from reliable information distribution tree overlay network.The lower part has a various of resources composed of network nodes.The use of hierarchical structure of the agreement possesses very good scalability and the multicast IP can connect the island to take full advantage of IP multicast efficiency,which are flexible according to specific selection domain corresponding application layer multicast protocol.The model has a lower control overhead,high bandwidth utilization and higher data transmission rate with an improved multicast performance.
