摘要：In this paper, we are minimizing the problems of congestion and delay in peer to peer network. In the existing system it allows the node to share a file in P2P networks and proposes the optimal sizing (number of peers) and grouping (number of directory intermediary) decisions. P2P technologies have many characteristics. First, no central control over the node and no single point of failure and are more scalable. Second, on a large P2P network, any node to find another node with the desired content that is close in which transmission delay may be lowered as well. The existing system has a drawback that only one supernode for each group; there may be problem when the supernode doesn‟t work properly and if the node doesn‟t want some particular files to be shared by other nodes in the network so, we are overcoming the problem by providing some backup (making a copy of the supernode) mechanism such that when a supernode fails to respond, the peer nodes can send request to the other node and for a node do not want to share a file with other node that can be overcome by privacy mechanism.
