存在一些基于内容散列ID机制的具有链接数据结构的分布式存储系统。在这样的系统中，用户需要等待遍历多个链接以到达所请求的数据。太慢的总响应时间可能会降低应用程序的可用性。如果该高速缓存系统运行在用户的站点上，它可以帮助减少用户请求的总响应时间。但是，没有适用于这种链接型数据结构的高速缓存管理机制。提出了一种适用于基于内容哈希ID的分布式存储系统的管理机制。所提出的机制是基于扩展的引用计数器。我们解释它作为一个具体的设计WOODS，这是一个简单的归档数据管理系统，我们已经提出。我们使用Gnutella查询的测量数据来评估所提出的缓存机制。
There are some distributed storage systems with linked data structure based on the content hash ID mechanism. In such systems, the user needs to wait to traverse multiple links to reach the requested data. Too slow total response time may degrade the usability of application. If the cache system is running on the user's site, it can help to reduce the total response time of user's request. But, there is no cache management mechanism that is applicable to such link type data structure. In this paper, we propose a novel management mechanism suitable for content hash ID based distributed storage system. The proposed mechanism is based on the expanded reference counter. We explain it as a concrete design for WOODS, which is a simple archiving data management system we have proposed. We evaluate the proposed cache mechanism using a measured data of Gnutella queries.
