摘要：为了解决分布式监测系统中大量数据传输效率低的问题，设计了一种计算机网络数据通讯机制，该机制定义了开放式系统通讯参考模型的传输层和表示层，传输层采用IP组播传输；表示层采用XML技术定义数据包，实现了网络数据的高效传输。通过与传统的单播方式的传输方式作实验对比，实验结果表明该方法能大大提高系统的数据通讯效率。

Abstract: In order to solve the problem of low efficiency of the huge data communication with each PC terminal in the system, a data ransmission mechanism was designed. Transmission layer and representation layer of system communication were defined, IP Multicast was adopted at transmission layer, XML technology was adopted to define data packet at representation layer. The transmission of network data efficiently was realized. Experimentation result shows that the mechanism can improve the efficency of system data transmission greatly.
Key words: IP multicast; XML technology; distributed monitoring and diagnosis system
