Design of High Performance Middleware for Dynamic Peer-To-Peer Networks

Abstract—This paper deals with a specially designed middleware (P2P Messaging System) that release the advantages of peer-to-peer networks to a broad spectrum of applications. The goal of this paper is to design a middleware for p2p networks that focuses on high-performance group communication based on a publish/subscribe model and its performance is compared with the JXTA technology. The P2P Messaging System considers the heterogeneous and dynamic character of peer-to-peer networks by an augmented topology and its supporting features. This paper gives a solution for an efficient group communication that is established by creating an Overlay networks to overcome topological limitations, implementing the Multi-ring topology to provide scalability, heterogeneity of Peers and decentralization, creation of Dual mode links to allow multiple message sources and to avoid message collisions and creation of Backup links to increase robustness
