本文简要介绍了承载弹性业务双层智能网络的模型,并介绍了模型设计的三个公式,这三个公式主要通过链路发生失败时业务流如何重新分配来区分,并通过数字的研究来比较三个重配置方式的效率。这些公式可以用来设计双层IPoverWDM结构的下一代核心网。
In this paper, a brief introduction of a model of a dual-layer intelligent network carrying resilient services is given. Three models of the model design are introduced. The three formulas are mainly distinguished by the redistribution of service flows in the event of a failure of the link and are compared by numerical studies The efficiency of the three reconfiguration methods. These formulas can be used to design next-generation core networks in a two-tier IPoverWDM architecture.
