摘　　要：产业界正在推进SFC（service function chain，业务链）技术发展，以实现云网融合的新型业务部署模式。业务路径选择策略是业务链的核心技术，直接影响网络性能与业务体验。针对现有业务路径选择策略存在的单一目标缺陷，创新提出并仿真验证了一种基于时延和负载的最小权重法，优化网络资源分配，提升业务链处理性能，为运营商未来网络和资源部署提供技术参考。In order to achieve the new business deployment model by the convergence of cloud and network, SFC technology has been promoted greatly. As one of the key technologies in SFC, the SFP selection strategy affects the network performance and business experience directly. Aiming at the single target defect existing in business path se- lection strategy, the minimum weight algorithm based on the network delay and load was proposed and simulated. It could optimize the resources allocation and improve the network performance. A technical reference was provided for the operators to deploy the network and resources in the future.
