The main device and the standby device of multi-machine backup need to use a channel to synchronize multi-machine backup state data and service data. The channel is created using a TCP connection. The channels of the multi-machine backup system comprise the following two types:
1) a control channel: the method is realized by establishing TCP connection between two devices in the multi-machine backup group. And the control channel synchronizes the state change information of the multi-computer backup example to the standby equipment in real time. In a multi-machine backup group, all multi-machine backup instances use the same control channel.
2) Service data channel: when the service is associated with the multi-machine backup instance, a service data channel (TCP connection) is created on the devices at the two ends of the multi-machine backup instance, and the service data channel is used for synchronizing the real-time state of the service and the service operation information, so as to ensure that the standby device can replace the main device when the main device fails, and the service is not interrupted.

In the technical scheme provided by the disclosure, the multi-channel separation of the connection of the main and standby machines comprises a heartbeat channel, a configuration backup channel and a session backup channel. The heartbeat channel is connected by UDP, so that the real-time performance of the heartbeat message and the quick response of the dual-computer state switching are ensured, and the heartbeat channel is not influenced by other backup messages. And configuring a backup channel as TCP connection, and ensuring reliable transmission of backup data by using the stream characteristics of TCP. The session backup channel is a two-layer message, and the message is forwarded through the MAC address and directly reaches the standby machine, so that the performance is high, the protocol stack is not limited, and the standby machine can be interconnected only by two layers.
The equipment in the main and standby system establishes UDP connection with the opposite terminal, after the heartbeat channel is established, the two machines interact information to select the main and standby, simultaneously establishes TCP connection used by backup configuration information, and establishes a two-layer transmission channel in the kernel through driving according to the information of interactive MAC and the like.

When the host equipment breaks down, the host equipment triggers election through the heartbeat channel, and at the moment, the health value of the standby equipment is higher, so that the standby equipment is upgraded to new host equipment, and the original host equipment is forced to become new standby equipment.
When the original host equipment is recovered from the fault, the original host equipment triggers election again, and at the moment, the health degree of the new host equipment is equivalent to that of the original host equipment, so that the main-standby switching does not occur. However, if the configuration of the original host device enables the preemption function, the original host device performs preemption, and after a certain delay, the original host device preempts and restores the host device, and the primary-standby relationship is adjusted accordingly.
When the connection of the heartbeat channel UDP is disconnected, the session backup channel is separated from the heartbeat channel, so that the session can be continuously backed up, and even if the traffic is sent to the standby machine at the moment, the session forwarding can still be matched.
