计算机网络中的高资源可用性已经成为一个关键问题，因为它可能受到网络用户数量增加的影响。提出了一种基于将网站访问者分类为优先级组的方法，确保优先级类的高可用性，基于只能由这些组访问的保留网站资源，同时提供尽可能多的资源，以降低优先级的访问者。提出了一个生灭过程来描述网站访问者的到达和服务。解决了一个优化问题，以确定高优先级访问者的资源可用性和低优先级访问者的免费资源访问之间的最佳权衡。本文的主要贡献在于推导出了网站访问者不再访问资源的概率公式，并确定了确保上述权衡的最佳保留资源
High resource availability in computer networks has become a critical issue as it can be affected by the increasing number of network users. A methodology based on classifying Website visitors into priority groups is proposed, assuring high availability for priority classes, based on reserved Website resources that can be accessed only by these groups and simultaneously providing as many resources as possible to lower priority visitors. A birth-death process is proposed to model Website visitors' arrival and service. An optimization problem is solved to determine the optimal trade off between resource availability for high priority visitors and free resource access to lower priority visitors. The major contribution of this paper consists in deriving formulas for the probability that a Website visitor has no further access to resources and in determining the optimal reserved resources assuring the above trade off
