Data message transmission method and related equipment

The embodiment of the invention discloses a data message transmission method and related equipment, which are used for improving the reliability of communication. In the application, a first network device receives a first data message sent by a second network device, and the first data message carries a standby address. When the first network equipment detects the link fault, the first network equipment can change the destination address in the first data message into the standby address to obtain the second data message, and then the first network equipment sends the second data message to the second network equipment, so that the loss of the first data message is avoided, and the communication reliability is guaranteed. 本申请实施例公开了一种数据报文传输方法和相关设备，用于提高通信的可靠性。在本申请中，第一网络设备接收第二网络设备发送的第一数据报文，其中，第一数据报文中携带备用地址。当第一网络设备检测到链路故障时，第一网络设备可以将第一数据报文中的目的地址改为备用地址，得到第二数据报文，那么，第一网络设备向第二网络设备发送第二数据报文，避免了第一数据报文的丢失，保障了通信的可靠性。
