Example 2
Embodiment 2 can be regarded as a preferable example of embodiment 1. The system for multi-lane communication timing control described in embodiment 2 uses the steps of the method for multi-lane communication timing control described in embodiment 1.
The invention provides a multi-channel communication time sequence control system, which comprises:
module S1: a sending end encapsulates the messages, adds a time sequence label to each message and transmits data through multiple channels;
module S2: the receiving end receives data from multiple channels, performs power-like operation according to the time sequence label, avoids repeated data receiving caused by multiple channels, and sends a packet back to the sending end after receiving is confirmed.

After receiving the message, the receiving end performs idempotent operation, and forwards the operated message to the service application layer for execution, and the service application layer does not consider the time sequence and mainly performs service processing of message data.
In a specific application, for example, a client device sends a certain data a through a TCP channel, a timing encapsulation is 1, if the TCP channel does not receive a response, the same data a is sent through a UDP channel, the timing encapsulation is also 1 as the same as the TCP, if the UDP channel does not receive a response, the same data a is sent through a short message channel, and the timing encapsulation is also 1 as the same as the TCP. The server side receives data of three channels of TCP, UDP and short message at the same time, if a certain channel receives data A first and the time sequence of the mark A is 1, then if the data A of other channels is received again and the time sequence is also 1, the data is considered to be repeated and ignored or recorded if the data A is repeated with the marked time sequence 1; if the received data timing is less than 1, i.e. the data is out of date, it is ignored or recorded.
