内容梗概 (abstract) In hierarchical Peer-to-Peer (P2P) systems, several selected peers are promoted as super-peers to provide an efficient lookup service for the ordinary peers, although this could cause a service bottleneck and a heavy workload at the point of the promoted peers. In this paper, we propose a two-level caching architecture consisting of a level-1 cache and a level-2 cache to relax such bottlenecks in hierarchical P2Ps. Each cache is partitioned into two parts so as to manage both static and dynamic data in a space-efficient manner: static data indicate popular pages which are frequently requested by many users and dynamic data indicate pages which may not be popular but are repeatedly requested during a short time period. The performance of the proposed method is evaluated by simulation. The result indicates that our caching protocol significantly reduces network traffic and exhibits a high hit rate even in small cache sizes.
