本文将排队论(又称随机服务系统)的思想和方法应用到校园信息网线路调节收费问题中，建立了相应于网络收费方案的用户与服务端口的M/M/n/n排队模型，对端口的利用率，用户能被服务的概率等，给出了合理的算式。合理的提出了该校网络按时间长收费的价格参照表。最后，对M//n/n排队模型进一步优化，在改进模型中，我们加入了用户网络流量与设备利用率的关系，从而使价格的制定更加合理，使设备的利用率进一步提高。文章还收集、整理了某高校校园网网络管理中的实际数据，代入模型进行实证分析，获得了相关技术指标。-In this paper, queuing theory (also known as stochastic service system) of ideas and methods applied to the campus information network in the line-conditioning charges, set up a charging scheme in the network of users and service port of the M/M/n/n queuing model on the utilization of the port, the user can be the probability of such services, given a reasonable formula. Put forward a reasonable time the school network by charging the price of the light table. Finally, the M// n/n queuing model was further optimized to improve the model, we joined the user utilization of network traffic and equipment, in order to enable the formulation of a more reasonable price, so that to further improve the utilization of equipment. The article also collect, organize a campus network in a practical network management data into the model, empirical analysis, access to the relevant technical indicators.
