Peer-to-peer (p2p) networking technologies have gained popularity as a mechanism for users to share files without the need for centralized servers. A p2p network provides a scalable and fault-tolerant mechanism to locate nodes anywhere on a network without maintaining a large amount of routing state. This allows for a variety of applications beyond simple file sharing. Examples include multicast systems, anonymous communications systems, and web caches. We envisage that an increasingly diverse set of applications will seek to make use of the growing pool of resources available around the edge of the network. here in this paper we brief the security and QOS issues of peer-to-peer networks that followed by current state of the art in handling these QOS and security issues.
