Adjacency cache: an efficient P2P web cache indexing and lookup system

摘要

This paper deseribes the design and evaluation of an ellicienl peer-to-peer (P2P) web cache indexing and lookup system, which ran be used to integrate the resources of locally available web pages into a globally addressable index using a distributed hash table. The salient feature of the indexing system's design is the efficient dissemination of cache index information using a next-url index which allows cai he clients to determine ahead of time whether linked content is also available at a remote cache. In addition, conventional optimizations such as in browser caching and batching of index write requests are. also used. These optimizations are evaluated using trace-driven simulation and the results show that these design trade-offs improve cache lookup performance.
