In this research, we focus on distributed network management in network coding. Web Services Distributed Management (WSDM) is one of the industry standards for distributed management. With the advantage of WSDM, we improve the efficiency of topology management in network coding and propose Distributed Topology Management System (DTMS). Under the campus network as our experimental environment, we analyze the performance of our system in this paper. Further, we compare the performance of our system with AdventNet Web NMS which is one of popular network management tools. Our work is the first solution to distributed network management in network coding. It is also the first to introduce WSDM specification to network coding. WSDM brings us a loosely coupling topology management system which is user-friendly and performs well.
