【摘要】 Gnutella网络采用洪泛式搜索机制,使网络具有高鲁棒性同时,也使网络产生了呈指数级增长的冗余消息.该文改进了Gnutella的搜索机制,提出了一种基于树结构的Gnutella-Tree搜索,并介绍了构造算法,给出了一种Gnutella自适应算法(Adaptive Gnutella Algorithm,简称AGA),以控制节点退出给Gnutella网络搜索带来的损失和网络的不稳定性,提高Gnutella-Tree搜索机制的鲁棒性.更多还原

【Abstract】 Gnutella uses the search mechanism of flooding.However,while bringing Gnutella network the characters of high robustness,this broadcasting mechanism makes that the network gives redundant messages that increase exponentially.This paper ameliorates Gnutella search mechanism,proposes a Gnutella-Tree search based on tree structure,and introduces its storage mechanism and a algorithm of Gnutella-Tree construct.A new Adaptive Gnutella Algorithm(AGA) is given,which is used to control the loss of Gnutella net search and net’s instability brought with peer exit.更多还原
