摘 要:
向基于P2P方式连接的CDN网络中的所有节点广播紧急消息,泛洪技术可以满足快速和可达这两个指标,但同时会在网络中产生大量冗余的消息广播,效率低下,使网络负荷产生一个短时的波峰。提出泛洪技术的两种改进方案,即WFES和WFESN技术,在不降低泛洪技术快速和可达的前提下提高了广播效率,改善了网络负荷的性能。[著者文摘]

Abstract:
WF( Water Flooding) can quickly broadcast messages to all the points in the networks. But at the same time, lots of redundant transmissions are generated. The technology of WF has exhibited its weaknesses, for example, low efficiency and bringing up a peak load. The research tried to make WF more efficient by proposing two improved technologies, WFES and WFESN. WFES and WFESN could improve the efficiency of broadcasting and performance of networks.[著者文摘]
Key words:
CDN; P2P; content delivery; water flooding
