针对具有网络流量非均衡特性的时延敏感业务, 提出一种并行调度两级轮询MAC控制协议。协议从服务策略和服务路径的角度实现了节点的优先级区分, 并且通过服务过程和查询转换过程的并行处理, 使得系统的时延特性显著提高。采用嵌入式马尔可夫链和概率母函数理论对提出的协议进行数学建模分析, 精确解析了系统的平均排队队长、平均循环周期、信息分组的平均等待时延, 仿真实验表明理论分析的正确性以及协议的有效性。

Aiming at the delay-sensitive applications with an unbalanced property of network flow, a new protocol called the parallel two-level polling control based MAC (PTLP-MAC) is proposed in this paper. The PTLP-MAC provides priority distinction from the aspects of the polling route and service scheme assignment. By proceeding with the data transmission and request parallel, the mean waiting time of the data packet is further reduced. Furthermore, by use of the embedded Markov chain and the theory of probability generating function, the mathematical functions were established and closed form expressions were given for obtaining the mean cyclic period, as well as the mean queue length and the mean waiting time characteristics. The analytical results were also verified through extensive computer simulations.
