该文研究了具有强分布式特征和分层结构的通信网络流量控制问题,借鉴多组博弈模型来研究新型的网络流量控制模型,构造了基于网络流量速率和时延为参数的流量效用函数,使之能适度地满足不同业务的用户流量QoS需求,利用多组博弈优化模型建立了基于Min-Max的公平的网络流量控制博弈模型。理论上证明了提出的网络流量控制模型的非劣纳什策略存在性。数值仿真验证了模型的正确性,仿真结果验证了用户流量在非劣纳什均衡点的效用值是帕累托占优的。

This paper investigates the communication network flow control with strong distributed feature and hierarchical structure, a novel network flow control model is studied by using the multi-team game model, the utility function is built up on flow rate and delay to make user flow satisfy different flow proportional QoS requirement, thus the Min-Max fair flow control game model is constituted by multi-team game optimized model. The existence of the non-inferior Nash equilibrium of the proposed network flow control model is proved theoretically. The correctness of the proposed model is validated by numerical evaluation, simulation result validates the user flow utility value is Pareto optimal at the non-inferior Nash equilibrium point.
