Design and Implementation of Double ID Space Based Peer-to-Peer File System
Fan Zhi-hua · Jisuanji gongcheng · 2005
The design and the implementation of DISPFS (double ID space based peer-to-Peer file system), a file system based on double ID space, provide a new method to solve 2 key points in file system: load balancing and file availability. In DISPFS, the base ID space provides virtual storage nodes to approach to system load balancing. The virtual storage node maintains k replicas of each file in its responsibility through which strong availability is guaranteed. The upper ID space offers efficient file distribution and file query through excellent peer-to-peer search service. DISPFS is an efficient and reliable peer-to-peer file systems, and it remains good performance under the conditions of heavy storage overhead and frequent file inserting or file disclaiming.
