摘　　要：面向服务提供的一体化承载网(UCN)的提出,增强了网络的可扩展性和可升级性,为实现三网融合提供了新的思路.如何有效管理UCN资源信息并且在物理资源有限的条件下构建出满足用户需求的逻辑承载网(LCN),是UCN研究中亟待解决的重点.文中给出了UCN的管理体系结构;提出了解决UCN资源拓扑发现和信息一致性问题的方法;建立了LCN构建数学模型,在构建策略的若干重要原则基础上,提出了带迁移同时考虑网络均衡的LCN构建方法;通过仿真实验,从构建需求接收率和构建后的平均链路利用率两个方面验证了该方法的有效性.To improve the extensibility and the ability of upgrading of the network, service oriented Universal Carrying Network （UCN） was proposed. A new solution of implying triple play was provided through UCN. How to construct Logical Carrying Network （LCN） which satisfies user＇s demand efficiently under the situation of limited resources is a hot issue in the research of UCN. The management architecture of UCN and solution to solve the problem of resource topology discovery and information consistency are proposed. Under this management architecture, mathematics model of construction of LCN is analyzed. Under some important principles a construction methods with migration based on network balance is given. All above give a new solution for the construction of LCN. The validity of the construction method is testified by emulation experiment through construction requirements acceptance ratio and average link utilization ratio.
