逻辑承载网构建效果评价方法研究

Research on Methods of the Logical Carrying Network Construction's Evaluation

逻辑承载网构建效果的评价是对一体化承载网的资源优化使用的重要手段。文章首先给出了物理承载网、用户需求和逻辑承载网等内容的具体数学模型,以描述逻辑承载网的特性。在满足用户需求的基础上,从物理承载网的剩余网络拓扑结构和资源分配均衡性的角度,使用图的连通性理论和概率论方法,提出了综合性的评价标准。

The evaluation of the logical carrying network＇s construction is an important approach to making use of the resources of the Universal Carrying Network. To characterize the logical carrying network, this paper introduces the mathematical model of the physical carrying network, requests of customers and logical carrying network. On the basis of satisfying the requests of customers, evalua- tions using the method based on theory of graph＇s connectivity and the theory of probability are intro- duced from the aspect of the remain network topology and distribution of network resources.
