基于QoS的分级选择策略

摘要

讨论了QoS组成要素，提出了一种基于QoS的分级顺序服务策略．该策略是在服务质量保证协议（QoSGP）的基础上，将用户分成不同优先权的三个等级，按优先权从高到低为：VIP用户、IP用户和Common用户，不同等级的用户采用不同的服务质量计算方法，等级内则采用顺序或随机顺序的服务策略．从实验结果可知，该策略满足了不同层次用户的请求服务质量要求，最大限度地让各用户满意，并提高系统的整体服务质量．%The elements of QoS are discussed and a level selection strategy of services based on QoS is proposed. System divides all the users into three different priority levels in the strategy, based on the QoS guarantee protocol （ QoSGP）, according to the priority from high to low： VIP users, IP users and Common users. Use different QoS calculation methods to different levels of users, and use ＂first come first do＂ or ＂random order＂ in the same level. From the experimental results, the strategy satisfies the user＇ s QoS requirements with different levels, and improves the system＇ s QoS.
