为了提高网络的可控可管性,解决实际网络管理中不同博弈理论集成所面临的动态决策和系统控制问题,分析了基于典型博弈理论的网络控制模型的基本特性,讨论了主从博弈、非合作博弈和合作博弈3种典型博弈问题的相关性,提出了以非合作博弈为基础的网络控制模型,包括资源最优控制层面和服务最优控制层面,分别实现对网络设备资源和网络服务请求的控制.该模型在博弈求解中考虑了时间变量的影响以及博弈实体在博弈过程中动态关系的变化轨迹,从所有博弈者的动态策略及目标状态的基本关系来解决网络博弈问题,最终形成一个能整合网络各要素的控制系统,并通过建立该网络控制模型的基本状态空间方程证明了该模型协同控制均衡态的稳定性.
To improve the controllability of the network and solve the problems on dynamic decision and system control while integrating different game theories used in the realistic network management,the relativity of the leader-follower game,the non-cooperative game and the cooperative game are discussed through analyzing the network control model based on the typical game theory.Then,the network control model based on the non-cooperative game is presented,which includes the resource control level and the service control level controlling the network devices and network services respectively.In order to solve the game,the time variable and the variation of the dynamic relations between game entities are taken into account in this model,and the control system integrating various network elements is formed based on the basic relation between the dynamic policies and object states of the game entities.Finally,the stability of the cooperative control equilibrium in this network control model is proved by establishing its basic state space equation.
