在异构网络环境中，数据实现高效、可靠与安全的分发，面临着不同的应用环境对操作系统、通信方式、网络协议以及服务质量( QoS)的多种要求。文中设计了一种基于DDS的，在异构网络通信中使用的数据分发系统。针对异构网络与DDS的特性，提出了异构网络数据分发系统的三层组织结构，并对每一层的具体内容，要实现的功能进行了研究。经过对异构网络中所传递的数据进行分析，结合OpenDDS本身的QoS策略推出该系统本身的QoS策略。最后，通过实验对该数据分发系统的网络延迟以及时延抖动进行了测试，表明了该系统能够有效满足异构网络之间的数据分发需求。

In heterogeneous network environment,to achieve efficient,reliable and safe distribution of data,face a variety of requirements of different application environments for operating system,communication method,network protocol and the Quality of Service ( QoS) . Based on DDS specification,design a data distribution system which is used for heterogeneous network. According to the characteristics of heterogeneous networks and DDS,propose the three layers of organization structure of heterogeneous network data distribution system, and study the specific content and function of each layer. Through analysis of the transmission of data in the heterogeneous network,com-bined OpenDDS's QoS strategy,launch the QoS strategy of the system itself. Finally,test the network time delay,jitter of the data distri-bution system through the experiment on itself,indicating that the system can effectively meet the demand of data distribution between heterogeneous networks.
