分布式存储系统以其分布式控制、自组织性和普遍的适应性而受到越来越多的关注。搜索是所有存储系统的重要组成部分,而对终端用户的反应时间是衡量一个搜索引擎优良的重要指标。讨论了目前几种流行的P2P网络搜索技术及特点,并比较其优劣,然后对基于分布式哈希表的搜索技术的几种改进方法进行了分析。
Interest in distributed storage system is fueled for its decentralized control, adaptation and self-organization. Search is an important technology for all storage system, and end-user latency is the most important performance metric for a search engine. Discusses several recent popular search technologies of P2P systems and characterizes of this technologies, and compares their advantages and disadvantages, then analyzes several improved ways for DHT-based storage system.
