本文先简述了ATM网络进行连接接纳控制(Connection Admission Control:CAC)的主要方法,其中主要综述了基于动态带宽分配的CAC策略,而后从合作对策模型的角度讨论业务间共享链路资源的公平性问题,提出一种基于时延带宽积的业务收益函数形式,并通过遗传算法求解待优化的对策函数,以决定对呼叫请求的接入或拒绝。仿真结果表明此方法能够更好地保证不同带宽和服务质量要求的业务共享网络资源的公平性。
In this paper, the main methods of ATM admission control (CAC) are briefly described. The CAC strategy based on dynamic bandwidth allocation is mainly reviewed. Then the fairness of sharing link resources between services is discussed from the perspective of cooperation strategy model This paper proposes a service revenue function form based on time-delay bandwidth product, and uses genetic algorithm to solve the countermeasure function to be optimized to decide whether to access or reject the call request. Simulation results show that this method can better ensure the fairness of network resources shared by different bandwidth and service quality requirements.
