摘　　要：随着民用飞瓤航电实际应用需求的不断发展，民机机载系统所实现的功能越来越纷繁复杂，未来民机机载软件系统如何适应分布式的、异构的环境，从而实现在不同平台、系统下的资源和数据共享是一个具有挑战性的问题。民机机载软件亟需在PC平台或嵌入式等典型运行环境下使用具有异构网络融合通信能力、并获取具有良好性能和移植性的数据传输协议。数据分发服务（DDS）技术具有异构网络传输能力、动态节点发现能力、数据传输质量约束功能等多种功能，满足民机机载软件数据传输需求。然而在各种或是资源受限、或是环境复杂的应用场景下能否保证DDS的性能是DDS研究和应用者必须回答的一个问题。通过研究DDS在各项目实际应用中经常出现的典型嵌入式和非嵌入式环境下的性能来对DDS的通信性能进行测试与评估。With the development of civil aircraft practical application requirements, civil aircraft airborne system functions become more and more complex. How could civil aircraft airborne systems adapt distributed and heterogeneous environments to realize resource and data sharing in different platforms and systems is a challenge. Civil aircraft airborne software need to use a data transmission protocol that has heterogeneous network communication ability in typical application environments like PC platforms or embedded systems, in order to possess better performance and transplant ability. Distributed data distribution service （DDS） possesses many functions such as heterogeneous network transmission, dynamic node discovery, data transmission quality constraint and suits civil aircraft airborne software data transmission requirements. However, in various kind of resource limited or complex environment, whether sound DDS performance can be ensured is a problem that DDS researchers and users have to answer. DDS performance in many kinds of typical application environments is evaluated and tested via research on the typical unembedded or embedded application environments usually appear in practical application of the projects.
