利用MTOM编码和异步调用改进流传输的性能

Improving the Performance of Streaming by Using MTOM Encoding and Asynchronous Calls

采用文本编码来格式化消息时会增加客户和服务信道之间的数据传输量,且随着文件长度的增加传输量会线性增长,其性能会大打折扣。WCF(Windows Communication Foundation)作为新一代的网络传输开发架构,其在构建面向服务的应用程序方面具有无比强大的生产力,本文以这个架构为蓝本,在消息层采用MTOM(Message Transmission Optimization Mechanism)编码构建SOAP(Simple Object Access Protocol)包,在传输层实现流模式,并利用异步调用提高应用程序的响应性能,可以显著提高文件流的传输性能。

When formatting message using Text Encoding, the data transmission will increase between the client and service Channel capacity. With the increment of the file length, throughput will increase linearly and its performance will be greatly reduced. As a new generation development architecture of network transmission, WCF （Windows Communication Foundation） has extremely powerful productivity in building the service-oriented application . This paper is to be modeled on this structure. The message layer constructs SOAP （Simple Object Access Protocol） package using MTOM （Message Transmission Optimization Mechanism） and the transport layer achieve streamming mode. The use of asynchronous calls can improve applications＇ performance of response. This program can significantly improve file stream transmission performance.
