服务承载网络是基于服务构建的以满足服务端到端QoS保障为出发点的覆盖网络,是满足可重构柔性网络对业务需求支撑的有效的网络架构。基于可重构柔性网络体系框架,分析服务承载网构建的主要问题,提出了可重构柔性网络下服务承载网的构建原则,在此基础上给出了基于势能导向多下一跳路由的服务承载网构建算法,并对其进行了性能分析及仿真。仿真结果表明,该算法具有较高的构建成功率。

Service overlay networks are overlay networks constructed to satisfy the end-to-end QoS. It is the most effi- cient network architecture to supply the traffic demands in reconfigurahle flexible network. Based on the architecture of reconfigurable flexible network, the dominant problems of service overlay networks construction were analyzed, and the construction principles were proposed. A construction algorithm based on node potential multi-nexthop routing protocol was also proposed. Simulation results indicate that the algorithm can archieve higher successful construction rate.
