容量有限非门限方式的逻辑环网建模与分析

Modeling and Simulating of a Class of Logic Ring Communication Network Based on Finite Capacity and Non-Threshold

讨论了具有以下特征的逻辑环通信网 :(1)系统队列容量有限 ;(2 )采用非门限服务方式 ;(3)服务数上额受限。阐述了该系统站点队列结构和运行特点 ,说明了其状态转移特征 ;提出了非门限方式中存在的步转移特殊问题 ;给出了此类系统有关工作特征参数的算法或近似算法 ,利用计算机进行运算 ,给出了在忽略溢出损失率时 ,容量和站点数不同时的部分参数的特征曲线。

It is discussed that a logic ring communication network has the following characteristics: (1) finite capacity; (2) non - threshold service mode; (3) upper limit of service number is limited. Alignment construction of station and characteristics of move and station state transfer are all stated. Special problems of pace transition existing in non - threshold service mode are put forward. Algorithms or approximate algorithms of system parameters about run are also provided, character curves of some parameters are provided by using computing when there are different capacity and number of station and loss rate of overflow is ignored.
