摘要
建立了 ATM网络 VP资源分配控制模型 ,并对其进行了分散化处理 ,使用动态规划求出分散模型下的控制律。仿真结果表明 ,尽管在性能上比集中控制稍有下降 ,但其可实现性和扩展性远远高于集中控制 ;与简单的反馈方案相比 ,降低了呼叫损失 ,提高了网络的利用率。
The model of the resource control problem of VP is established and then decentralized. The decentralized control law is obtained by using the dynamic programming. Though it is not optimal as compared with the centralized method, it has less call loss with respect to the simple feedback control and the efficiency of networks has been improved. It is also easy to realize in true networks.
