A Hierarchical Protocol Structure in Distributed Virtual Environment
一种适合于分布式虚拟环境的层次式协议结构

With the demands of information interaction increasing in distributed virtual environment (DVE), interest filter based on interest expression can't satisfy requirements now, the proposal of XML router technology gives new drive to improving the scalability of DVE. Followed by analyzing the protocol structure of interest management based on interest expression, this paper introduces task expression of dynamical information by illustrating virtual museum, and proposes the schema of XML-based encapsulating protocol according as its potential hierarchical structure, which will be adapted to XML router-based active network better.
