In the recent years, the development of a new wave of innovative network architectures labelled (p2p) has been observed. A peer to- peer (P2P) network is a dispersed system in which peers utilize dispersed resources to execute a significant function in a decentralized fashion. Nodes in a P2P network usually play identical roles and these nodes are called peers. P2P networks can be divided into two categories: structured peer-to-peer networks in which peers are associated by a normal topology, and unstructured peer-to-peer networks in which the topology is random. To design a hybrid peer-to-peer system for dispersed data distribution which combines the advantages of both types of peer-to-peer networks and reduces their disadvantages is the objective of our work. Reliability preservation is propagating the updates from a primary file to its copy. Adaptive consistency maintenance algorithm (ACMA) upholds that periodically polls the file owner to update the file due to lowest number of replications reliability overhead is very low. Top Caching (TC) algorithm helps to enhance the system performance and to construct a fully dispersed cache for mostly accepted information. Our caching system can deliver lesser query interruption improved load balance and higher cache hit ratios. It efficiently alleviates the over-caching problems for the most accepted objects.
