摘　　要：随着民航空管越来越多的IP类业务接入网的建设和运行,多业务路由器应用越来越多,传输异常和流量管理问题也日益凸显,需要运维人员对其进行系统性学习和积累故障维护经验。文章主要描述了西南空管局成都两场四地IP接入网路由器之间因存在超大流量,造成设备数据转发CPU超负荷工作,导致业务数据丢包的一起典型故障;详细分析了故障原因,并给出解决方案。最后结合此故障对民航IP类网络的流量管理进行分析探讨,此起故障分析和流量管理措施可为民航空管类似网络的建设及运维提供借鉴。With the increasing construction and operation of IP-based business access networks in civil aviation air traffic control,the application of multi-service routers has become incrcasingly prevalent,and transmission abnormalities and traffic management issues have also become increasingly prominent.Operational and maintenance personnel need to systematically learn and accumulate fault maintenance experience in this regard.This article mainly describes a typical fault in the IP access network routers between the two airports in Chengdu,Southwest Air Traffic Management Bureau,caused by excessive traffic,resulting in overload of the device's data forwarding CPU and packet loss of business data.The article analyzes the cause of the fault in detail and provides a solution.Finally,based on this fault,the article analyzes and discusses the traffic management of civil aviation IP networks.The fault analysis and traffic management measures can provide a reference for the construction and operation of similar networks in civil aviation air traffic control.
