摘　　要：提出了一个优化的IP-DiffServ实时记费管理机制。在SLA协商时和某个业务类满负荷时,该机制通过对用户业务和用户业务应用实施业务计划,为它们定义最优化的业务类。通过闲置价格、使用价格和拥塞价格的多价格体系,对用户业务进行基于使用量的实时计费。它不但可以提高网络的QoS保证能力、提高网络的抗拥塞能力以及维持用户业务价格稳定,而且可以提高网络提供业务的性能价格比。实验结果很好验证了该机制的优点。This paper addresses an optimal accounting management mechanism for IP-DiffServ network.During SLA coordination and when a service class burden bound arrived,it can select optimal service class for user service and service application by running its service plan program.By using holding price,usage price,as well as congestion price, it charges the user service on line.Not only can it improve the ability of QoS assurance,but also it can improve the ability of congestion recovery,keep statistical price stable as well as provide well performance with less cost. Experimental results have perfectly verified its merits.
