本文针对卫星网络资源有限的情况下,特别是当卫星网络带宽迅速降低至难以保障所有数据流的基本带宽时,基于服务满意度和中断服务不满意度的概念,设计并实现了一种面向服务满意度的数据流接纳控制决策机制.该决策机制给出了在无数据流中断模式下的最优求解算法和有数据流中断模式下的近似最优求解算法,对所有数据流进行接纳控制决策,决定各条数据流的通断情况及各自的带宽值,使得服务满意度达到最大.通过配置数据流对接纳控制决策机制进行仿真测试,实验结果验证了该决策机制在解决接纳控制决策优化问题上的优越性.
In this paper, aiming at the limited resources of satellite network, especially when the bandwidth of satellite network is rapidly reduced to the difficulty of guaranteeing the basic bandwidth of all data streams, this paper designs and implements a Service Oriented Satisfaction of the data flow admission control decision-making mechanism.The decision-making mechanism gives the optimal solution algorithm without data flow interrupt mode and the approximate optimal solution algorithm with data flow interrupt mode, all data flow admission control decision , Determine the data flow on and off and their respective bandwidth values, so that the maximum service satisfaction.Configuration data flow simulation of admission control decision-making mechanism, the experimental results verify the decision-making mechanism to solve the admission control decision-making optimization problem On the superiority.
