Abstract Proposed a system for the purpose of idle resource utilization of the computer using the P2P Satoshi YANASE Recently, researches about system combined cloud and P2P to improve efficiency of resource sharing have been proposed. However, systems that can share peers processes that should be processed in real time have not been proposed, In this paper, in order to share processes of peers we propose a system adopts hybrid P2P network model and enables to reduce processing delay due to performance differences. By comparing performance of each peer and grouping the peers, the system can be responsible for high processing with peers processing capacity. To evaluate our proposal system, we implement our proposal system on a simulator. We evaluate our proposal system in terms of increase or decrease of peers. key words P2P, Load sharing ii
