摘要
在多业务共享网络资源的环境中,为了进行有限带宽资源的优化配置,实现运营商的收益最大化,分析了典型业务的流量特征和质量需求,改进了支持业务质量(QoS)保证的运营商收益最大化的定价模型;基于该模型目标函数取最优值的充分必要条件,简化了求解目标的二分查表搜索算法.典型业务实例分析和仿真实验结果表明,与基于资源占用量的定价机制相比,该定价机制能获得更优的运营商收益.
In order to optimize allocation of the limited bandwidth resources and maximize the operator＇s profit in environment of multi-services sharing network resources,some typical services＇ traffic characteristics and quality requirements are firstly analyzed,and the quality of service（QoS）-based pricing objective of operators＇ revenue maximization is proposed.Based on necessary and sufficient conditions of maximizing the objective function,the binary search algorithm for optimal solution is proposed.The case analysis and experiments show that the pricing mechanism proposed can achieve better revenue compared with resource usage based one.
