【摘要】 一种基于效用模型的网络拥塞定价策略引入了用户可承受价格、用户满意度等因素,建立网络拥塞控制的效用模型。可以优化网络资源分配,避免网络拥塞。在满足QoS指标的条件下,模型利用供求相互作用机制、价格调节机制等寻找用户满意度和网络性能的最佳结合点,从而对网络资源进行最优分配,并均衡网络负载。仿真实验结果验证了该策略的有效性和可行性。更多还原

【Abstract】 In this paper,we present a utility model-based network congestion pricing strategy to optimize the resource allocation and avoid network congestion.This pricing strategy takes into account the dominant factors such as the buy prices and customer satisfaction to construct a utility model for network congestion control.Under constrained QoS conditions,the model exploits the mechanisms including interaction between supply and demand,and price adjustment,to take a trade-off between the customer satisfaction and network performance.Optimal resource allocation and load balancing are achieved by adopting our model.Experimental results demonstrate the efficiency and feasibility of our pricing strategy.更多还原
