摘要：Peer-to-peer overlay networks are widely used in distributed systems. P2P networks can be divided into two categories: structured peer-topeer networks in which peers are connected by a regular topology, and unstructured peer-to-peer networks in which the topology is arbitrary. The objective of this work is to design a hybrid peerto- peer system for distributed data sharing which combines the advantages of both types of peer-to-peer networks and minimizes their disadvantages. Consistency maintenance is propagating the updates from a primary file to its replica. Adaptive Consistency Maintenance Algorithm (ACMA) maintains that periodically polls the file owner to update the file due to minimum number of replicas consistency overhead is very low. Top Caching (TC) algorithm helps to boost the system performance and to build a fully distributed cache for most popular information. Our caching scheme can deliver lower query delay, better load balance and higher cache hit ratios. It effectively relieves the over-caching problems for the most popular objects.
