在对分布式虚拟环境应用特点和已有事件匹配算法进行研究和分析的基础上,设计并实现了一种基于内容的快速事件匹配算法。该算法兼顾了处理订购和事件匹配的效率,能够有效地解决对称事件匹配问题,从而使基于内容的发布/订购模型能较好地应用于分布式虚拟环境。实验结果及性能分析证明了该算法的可行性和有效性。
Based on the study of characteristics of the distributed virtual environment and current event matching algorithms, a content-based effective event matching (CEEM) algorithm was proposed. By considering the efficiency of both subscription processing and event matching, this algorithm can solve the symmetric event matching efficiently, so as to make the content-based publish/subscribe model fit the virtual environment better. Finally, experiments and performance analysis show that CEEM is both practical and effective.
