Research on XML-based active interest management in distributed virtual environment

Abstract

The essential problem of Distributed Virtual Environment (DVE) is to build scalable communication architecture, on which a large number of objects can communicate each other in a dynamical fashion. In this paper, a new XML-based scalable active interest management approach, which applies active routing technique to interest management, is presented to provide a heuristic method to solve the traditional scalability problem in DVE. The new approach uses XML to describe the interest representation model of objects, and implements active package filtering and transmission by XML routers based on the bi-directional shared multicast infrastructure. We developed the prototype system, and performed experiments in campus network. Experimental results show that this approach can prevent hosts from receiving redundant packets, thus efficiently reducing the total traffic in virtual environment. © Springer-Verlag Berlin Heidelberg 2007.
