中文摘要：
可重构信息通信基础网络通过构建服务承载网的方式为业务提供自适应的承载服务。针对高效利用有限底层资源的问题,提出一种基于资源关键度进行动态映射的服务承载网构建算法。算法将通过节点或链路的最短路径数作为资源关键度的衡量指标,区别对待底层资源;并实时动态感知关键资源的使用状况,依据不同业务需求对服务承载网进行自适应调整。仿真结果表明,算法在构建成功率、收益花费比和资源均衡度等方面均具有良好性能。
英文摘要：
Reconfigurable information communication basal network supports self-adaptive services to applications by constructing reconfigurable service carrying network（RSCN）. To effectively utilize the limited substrate network re- sources, an algorithm of dynamic topology awareness-based RSCN reconfiguration （DTAR） was proposed. The algorithm uses the number of shortest paths as resource critical degree which across the node or link to distinguish substrate re- source. And it also dynamically awares the states of critical resources, reoptimises the RSCN according to service request. Experimental results show that comparing with the existing algorithms, the proposed algorithm achieves higher success ratio, gains higher revenue, cost ratio and load equilibrium for substrate network.
