摘　　要：随着航空电子系统模块化技术的发展,系统内大数据传输的需求越来越多,现有的大数据传输方式或需要更改系统架构,或需要系统具有特定功能支持,难以在不同的航空电子系统中进行广泛应用。提出一种多窗口传输协议,并给出其实现方法,该协议使用额外的资源同时进行多窗口信息传输,以保证在机载网络不稳定环境下传输的速率和稳定性。试验表明:本文提出的多窗口传输协议能够满足系统大数据传输的需求,且该方法在应用层实现,避免了对系统现有硬件和软件架构的更改,适用范围较广。As technique of integrated modular avionics developing, the requirement of large data transfer is increasingly clear. Methods currently used either need to modify existing architecture or need specific functional support from operating system, which limits their application in different avionics systems. In order to solve this problem, a multiple window protocol as well as its implementation is proposed in this thesis. This protocol applies extra resource to keep transferring multiple windows and remains high stability and efficiently while working in unstable airborne networks. Therefore, it can meet the requirement of efficiency and stability of large data transferring in avionics system. And also, this protocol can be implemented at application level;there is no need to modify existing system architecture. This character makes it have a wild range of application.
