A major asset provided by code mobility is that it enables service customization.In conventional distributed systems built following a C/S paradigm, servers provide a priori fixed set of services accessible through statically defined interfaces. It is often the case that this set of services are not suitable for unforeseen user needs, the solution to this problem is to upgrade the system with new functionality, thus increase the system's complexity and size but the flexibility. Conversely code mobility can solve this contradiction by transferring new functionality codes to user without increasing system's size and complexity. However, the deadly defect in code mobility is network cost caused by transmitting, how to control the cost is an open problem. Fortunately, the researchers in distributed system domain have proposed several ways to get point on it. Rationally moving resource components provided by the mobile agent system among the network nodes is one of them. This article gets the point on reducing the network cost intra the MA architecture and last getting the best performance in all. We introduced a component reconfiguration model created by Avrampopoulos, and we make an improvement based on the original model , name it MA-RDC model. After that, we analyses the communication methods already exited internationally, and provide a new compound method to satisfy model MA-RDC's needs.
