摘　　要：移动通信核心网同时接入和处理通话业务与上网业务,其可靠性是保障业务永续性的基础。论述了双向转发检测(Bidirectional Forwarding Detection,BFD)协议在核心网中应用的工作原理、工作模式、报文格式等,明确BFD协议应用的可行性。同时分析了BFD协议与核心网中虚拟路由器冗余协议、内部网关协议、快速重路由等的联用,以此促进BFD协议在通信核心网中科学合理的规划部署,从而实现核心网毫米级故障检测、故障处理、网络恢复等功能,提高核心网运行的可靠性。The mobile communication core network simultaneously accesses and processes call services and Internet access services,and its reliability is the basis for ensuring business continuity.The working principle,working mode and packet format of the Bidirectional Forwarding Detection(BFD)protocol applied in the core network are discussed,and the feasibility of the application of the BFD protocol is clarified.At the same time,the combination of BFD protocol and virtual router redundancy protocol,internal gateway protocol,fast rerouting,etc.in the core network is analyzed,so as to promote the scientific and reasonable planning and deployment of the BFD protocol in the communication core network,so as to realize the millimeter-level failure of the core network detection,fault handling,network recovery and other functions to improve the reliability of core network operation.
