When distributed object technology is used in a wide area network, large delay causes inefficient access to an object. For this problem we propose a replicated object relocation protocol called RORP, where the replicated object is relocated to an intermediate site considering communication delay, processing ability of servers, reference frequency of objects, time of object transmission, domain and limited number of replications. The paper describes the protocol and discusses its performance through an implementation of RORP prototype. We evaluate the client oriented replication scheme by processing amount distributed to clients, intermediate sites and servers. In addition the paper shows how RORP enables reduction of a response time and total network traffic including control messages and object retrieval messages
