摘　　要：基于XML的SOAP协议使得Web服务与其他分布式计算模型如EJB、CORBA和DCOM等相比,在性能上有相当的差距,这影响了其应用.本文提出了一种基于Context-Store的SOAP消息优化方法,将消息分为静态消息部分和动态消息部分,尽量避免消息的冗余部分在网络中的多次传输,大大节省了带宽,提高了SOAP消息的传输速度,从而改善了Web服务的性能.实验结果表明,基于Context-Store的Web服务性能明显高于常规SOAP消息和压缩SOAP消息方法.Web services, which generally utilize XML- based SOAP as a data exchange protocol, can hardly achieve the same high performance as other distributed computing technologies. In this paper, we present a SOAP message optimization method based on ContextStore. In order to help minimize such overheads, we separate data content from the SOAP message syntax. The redundant or sradc message parts are stored in a shared meradara space--the Context - Store, so it may avoid transferring the redundant part of message in network and improve the web services performance. The empirical results show that our method outperforms conventional SOAP message process method and SOAP message compression method.
