摘　　要：针对窄带宽、弱连接和高动态的行业专用无线通信网络,通过使用一种软件定义网络集中控制与分布式路由控制共存的混合组网架构,解决传统分布式组网业务服务质量无法保障等问题。此外,针对软件定义网络架构的控制开销大、抗毁性差等问题,在混合组网架构基础上对转发面进行优化,提出了路由转发与基于段路由受控转发共存的转发模式,以节约控制开销、增强抗毁性。通过混合组网架构设计、控制器部署方式优化、南向接口轻量化、分布式组网扩展和转发面升级等方式,为集中控制与分布式路由控制在专用无线通信网络的综合应用提供了解决方案,以较低的控制复杂度大幅度提升专用无线通信网络的服务质量保障能力和转发效率。Aiming at dedicated wireless communication networks with narrow bandwidth,weak connection,and high dynamics,this paper address issues such as the failure to guarantee the service quality of conventional distributed networking services by using a hybrid networking architecture that combines SDN centralized control and distributed routing control.In addition,in response to the high control cost and poor survivability of SDN architecture,it optimizes the forwarding surface on the basis of hybrid networking architecture,and proposes a forwarding mode in which route forwarding coexists with controlled forwarding based on segment routing to save control costs and enhance survivability.This paper provides a solution for the comprehensive application of centralized control and distributed routing control in dedicated wireless communication networks through hybrid networking architecture design,optimized controller deployment,lightweight southbound interfaces,distributed networking expansion,and upgrade of forwarding surfaces,which significantly improves the service quality assurance ability and forwarding efficiency of dedicated wireless communication networks with lower control complexity.
