摘要

对现有的时分多址（TDMA）宽带卫星网络的不同时隙分配协议进行了比较

提出了基于业务预测的突发目标按需分配（BTDAMA—PA）协议。对按需与自由分配相结合（CFDAMA）、纯按需分配BT-DAMA与基于预测的BTDAMA—PA协议进行了比较

并以典型的具有自相似特性的Pareto ON/OFF信源进行仿真分析

结果表明:相比CFDAMA和BTDAMA

BTDAMA—PA协议在地面终端业务量变化情况下

可以获得更小的平均端端延迟和时延抖动

尤其是系统负载趋于饱和时

平均端端时延减小约20%

时延抖动减小约40%。

Abstract

Performances of timeslot assignment protocol of the existing time division multiple access（TDMA） broadband satellite network are compared

and an improved BTDAMA protocol based on prediction is proposed.CFDAMA

BTDAMA are compared with BTDAMA-PA.Simulations analysis on typical with selfsimilarity Characteristics Pareto ON / OFF source is carried out and the result shows that the new protocol BTDAMA—PA outperforms CFDAMA and BTDAMA in decreasing average end-to-end delay and jitter.Particularly

average end to end delay and time delay tremble can be obtained under heavy system load

which is decreased by 20 % and 40 % respectively.
