对邻近空间链路协议功能的研究

邻近空间链路协议是一项专门应用于邻近空间链路的新型空间通信协议。为了能尽快地在国内实现该协议，文中从以下几个方面对其进行了分析：邻近空间链路协议的功能层次模型、各层的功能。尤其对功能实现中的两个关键问题——MAC子层的持续行为程序和帧子层确定帧传榆顺序的策略进行了深入的分析研究，并提出了相应的解决方案。

Research on Function of Proximity-1 Space Link Protocol

Proximity-1 Space Link Protocol is a new space communication protocol developed specially for the proximity link. To accelerate its implementation in China, this paper analyses the protocol from the following aspects： the layered function model and the function of each layer. Especially, this paper describes the researches on the two key problems in the function realization. The two key problems include the persistent activity process in MAC sublayer and the priority scheme of the frame transmission in frame sublayer. And also, this paper proposes the solutions for these problems.
