摘　　要：为提升Web服务性能,满足其进一步应用的要求,研究了消息传输优化机制(message transmission optimizationmechanism,MTOM)。针对基于Web的二进制数据传输,MTOM采用不同于传统内嵌Base64编码的方式,而是作为附件处理,压缩了报文,提高了性能。在理论分析的基础上,设计并构建了一组Web服务原型。通过一组对比实验,跟踪传输层报文验证了原型的正确和实际报文的缩减。实验结果表明了MTOM对Web服务性能近30%的提升。To promote the performance of Web Service, and satisfy its further developing requirement. The message transmission optimization mechanism （MTOM） is studied, aiming at the webbased binary data transfer, MTOM deals with the data as attachments which is different from the traditional embedded Base64 encoding style. As a result, the message is compressed and the performance is promoted. Based on the theory analysis, a set of Web Service prototypes are designed and constructed. After a group of parallel experiments, the messages in transport layer are traced to verify the accuracy of prototypes and the compres sion of actual messages. Finally the effect that MTOM could make a nearly 30 percent promotion is demonstrated by the data.
