摘要
从满足多业务类型通信业务的要求出发对轮询多址门限服务系统进行研究,提出一种支持多业务类型的门限服务轮询多址系统模型,该模型在非对称轮询多址服务机制的基础上减少了服务器查询排队队列的门限判决时刻,在此基础上采用嵌入马尔科夫链和概率母函数的分析方法,得到该模型中各队列平均排队队长以及信息分组发送等待时延的数学解析,通过计算机仿真实验对该理论分析结果加以验证.
The multi -service threshold polling system (MTPS) was analyzed. It could be used for the communication systems with different service types. The queue schemes are improved by reducing the queue threshold time. Methods of the imbedded Markov - chain theory and the probability generating function are used to obtain the mean queue length and information packet waiting time. Analytical is in accordance with the result of computer simulation.
