For the speciality of P2P(peer-topeer) computing environment,the tranditional technique of component integration usually cannot be directly employed in this case.In the paper,some key problems which are encountered during the process of integrating components for P2P computing environment are studied,and the corresponding solutions are proposed.These problems include the relationship between connections and ports,the communication patterns,the cocurrent execution of deferent components on deferent peers,and the efficiency of transformation of big objects.Based on the proposed solutions,an implemental framework,called PeerCOM,is designed.
