Computer network technologies have been growing explosively and the study in computer networks is being challenging task system participants want to get the final result, In this research work central node may become overloaded, especially if many nodes request the result at the same time. This work present a proposal to build a high throughput computing system totally based upon the Peer-to-Peer (P2P) paradigm. In this work discuss the general characteristics of P2P systems this way we avoid overloading the central node, as well as network congestion we assume that the computing system works on the top of an overlay network. Here present a complete description of the P2P computing system shows a classification of the tools used in communications networks. And we discuss how different simulation tools used in different area like educational research, commercial research is done on P2P system.
