在多层网络的资源配置中,为了实现备份资源在各网络层的最大共享,在综合考虑网络各层的资源使用信息和拓扑信息的基础上,提出了一种联合的资源配置方案.在建立资源分配方案的整数线性规划模型的同时,提出了适合解决大规模网络的遗传算法.数值结果表明联合资源配置方案可以更好地共享各网络层的备份资源,从而使多层网络具有更高的带宽利用率和更低的运营成本.由于引入了各网络层的协调,从而防止了回路问题.
In the multi-layer network resource allocation, in order to achieve the maximum sharing of backup resources at each network layer, based on the comprehensive consideration of the resource usage information and topology information at all levels of the network, a joint resource allocation scheme is proposed. Resource allocation scheme is proposed, and a genetic algorithm suitable for large-scale network is proposed.Numerical results show that the joint resource allocation scheme can better share the backup resources at each network layer, so that the multi-layer network has a higher Bandwidth utilization and lower operating costs As a result of the coordination of the various network layers introduced, loopback problems are prevented.
