摘要

在基于内容分发网络和对等网络的混合流媒体系统中引入基于资源知名度的混合搜索机制，依据不同的资源知名度，分别采用结构化搜索和泛洪搜索，提高了搜索效率。结构化部分采用改进型Chord 搜索机制，其路由时延较传统Chord搜索大幅度降低；泛洪部分采用基于布鲁曼滤波器的泛洪搜索，相比以往的泛洪搜索，网络中的冗余查询消息明显减少。此外，系统还根据资源知名度的不同分别采用多关键字查找和语义相关度匹配来支持资源的模糊查找，提高了搜索成功率。

Abstract

A hybrid resources search mechanism based on the popularity of resources was proposed in the hybrid peer to peer stream media system based on CDN and P2P.A different search mechanism was used according to the different popularity of resources，such as structured search or flooding.By this way，the efficient of search was effectively improved.In the part of structured search，an improved Chord search mechanism was proposed.Compared with the traditional Chord search mechanism，the router delay was greatly reduced.A flooding search mechanism based on bloom filter was proposed in the part of flooding.Compared with the traditional flooding search mechanism，it can significantly lower the redundancy transmission of search request.Also，according to the different popularity of resources，multi-keyword query and the concept of semantic correlation were proposed to support fuzzy search，and the rate of successful search was greatly increased.
