摘　　要：逻辑承载网构建将网络服务需求映射到物理网络,以增强网络服务的可扩展性。为解决构建效率问题,借鉴负载均衡思想,提出了对不同服务需求提供不同网络资源的按需承载策略,并基于可用资源和链路负载状态,用改进的多物质流模型进行优化计算。通过仿真实验,从构建成功率、构建平均收益等方面验证了算法具有更高的网络服务提供能力。To improve the extensibility of network service,constructing algorithm of logical carrying network was pro-posed by mapping the demands of network service into substrate network.To solve the problem of construction efficiency,on-demand carrying strategy was introduced to provide different resources to meet different service requirements.Based on available resource and current link load,an improved multi-commodity flow model was proposed to compute the re-source allocation.Simulation results indicate this algorithm can improve network service capability from construction success rate and average construction profit.
