摘　　要：讨论了校园网格计费问题.分析了校园网格计费的特点,提出网格银行系统概念,引入多维服务质量(QoS)概念,建立了基于QoS的层次化校园网格计费模型.该模型由一个总行组件和若干个分行组件构成,总行组件部署在中心服务器,实现上层的认证、记账和结算;分行组件部署在各个资源域,实现下层的定价和算法.使用动态资源价格,实现由多维QoS到一维费用的算法.研究表明,模型适应校园网格的特点,可减轻服务器负担,反映资源使用情况,能更好地满足校园网格计费的需求.This paper discussed accounting system for campus grid. The characteristics of accounting system for campus grid are analyzed.The concepts of gridbank system and multidimensional QoS are introduced to build the hierarchical accounting model based on QoS for campus grid which consists of a headquarters and some branches.The headquarters in the center server performs the functions such as authentication,account and settlement.The branch in resource domain performs the functions such as price and algorithm.The algorithm which gets cost by multidimensional QoS with dynamic price is proposed.It suits the characteristics of campus grid and can reduce the load of the center server and reflect the usage of resource.
