摘要
基于已有的市场模型下的带宽分配算法,从系统收益和用户平均满意度出发,提出一种改进后的基于定价机制的带宽分配算法。该算法根据用户的需求和网络系统带宽的使用状况,计算出网络带宽的价格,并采用集中竞拍的方式,通过用户的价格参数进行带宽资源的协商与分配。仿真分析表明,该方法可以达到提高用户满意度和优化系统效益的目标。
A new improved pricing-based approach is presented in consideration of mean users＇ satisfaction and system＇ s revenue based on main current method of bandwidth allocation based on market, The price of the bandwidth is calculated based on the bandwidth demand of users （i.e. applications or flows） and the bandwidth usage of the network system, which is used together with users＇ price parameters to regulate bandwidth allocation. The simulation result shows the effectiveness in improving users＇ satisfaction and the systems utilization.
