香港科技大学的p2p综述

P2P network is factually an overlay network for distributed object store, search and sharing. This paper will present a survey about it’s recent. First, we will introduce a simple definition of P2P, and define some common operation procedures in P2P. Second, P2P performance metric will be discussed in order to understand and differentiated the practical P2P architectures and protocols. Third, the current P2P architecture will be classified and compared in detail. Then, object search protocols will be carefully discussed with corresponding P2P architecture. We also review the current P2P modeling outputs and list the general modeling approaches. Finally, several novel applications based on P2P techniques and future research directions of P2P overlay networks are briefly investigated. This paper aims to give a clear and complete survey of P2P networks according to clues of its development and evolution process.
