| 摘 要： | 为了对基于轮询机制的通信系统进行理论设计和性能评价，需要对平均排队队长进行定量分析。本通信系统采用了基于完全服务的非抢占排队优先权轮询机制作为信道共享策略。首先建立了系统分析的数学模型，然后利用嵌入马尔可夫链理论推导出系统的概率母函数。通过对系统一阶特性的迭代计算，最终解析出非对称情形下的平均排队队长表达式，并且利用计算机仿真实验证明了分析的有效性。 |
| 关 键 词： | 完全服务轮询系统 非抢占优先权 一阶特性 平均队长 |

| Abstract: | In order to design and value a polling-based communication system, quantitative analysis of mean queue length is a key point. No-interrupted priority queue polling mechanism with exhaustive service is applied as a channel accession policy in the communication in this paper. Based on a mathematic model, the generating function of system is deduced by imbedded Markov chain theory. Moreover, mean queue length expressions of asymmetric system are obtained explicitly via iterative algorithm on the first moments of the system, and simulation results demonstrate effectiveness of analysis. |
| Keywords: | polling system with exhaustive service no-interrupted queue priority first moments mean queue length |
