Abstract: Based on the analysis of XML routing techniques,a new method is presented to implement distributed virtual environment using XML routing.Combining XML routing techniques with active interest management,this method adopts the b-i directional shared multicast tree as the communication topology, and performs active filtering and forwarding of datagram according to publish-subscribe pattern.Therefore, this method can not only reduce network traffic,but also quickly change communication relationship in a dynamical fashion,thus efficiently improving the scalability of distributed virtual environment.Finally,the implementation of the prototype system demonstrates the feasibility and efficiency of the method applied in the distributed virtual environment.
