CCSDS 高级在轨系统复接业务性能的分析

ANALYSIS OF PERFORMANCE OF MULTIPLEXING IN CCSDS FOR ADVANCED ORBITING SYSTEMS

本论文分析了空间链路子网上的异步业务特别是复接业务的性能，建立了一种异步信息模型，从而解决了平均包延迟，帧效率的问题。这个结果也适用于各种不同的信息配置下可获得的系统性能的上、下限。而且，本文还讨论了一组与执行相关的参数，如帧完成暂停时间（ｆｒａｍｅｃｏｍｐｌｅｔｉｏｎｔｉｍｅ＿ｏｕｔｐｅｒｉｏｄ）。

In this context,the CCSDS has worked toword the definition of a digital satallite network offering a wide variety of services This paper analyses the performance of the asynchronons services especially multiplexing service across the Space Link Subnetwork A model for asynchronous traffic is developed,generating the solution for packet average delay,frame efficiency The results are also useful in providing an upper and lower bound to the system performance attainable under variety of traffic configurations Moreover,a setting of implementation—dependant parameters,such as frame completion time—out period is discussed in terms of its imfluence on system performances
