Peer-to-peer networks are used in distributed systems. Normally P2P networks are classified as Unstructured and Structured networks. In structured peer to peer network, peers are connected in a regular topology while in Unstructured, they are connected arbitrary fashion. Objective of this paper is to develop Hybrid peer to peer network, which will overcome all the disadvantages in both structured and unstructured network and also improve the caching scheme in this network.
