Abstract: A first aspect of embodiments of the present application provides a communication method. In the method, a first node acquires a target information element and a target time point. The target time point is used to indicate a time point at which the target information element is processed. During transmission of the target information element from the first node to a lower-level node in a switched network system, only when a difference between a system time point of the first node and the target time point is greater than a delayed transmission threshold, does the first node transmit the target information element to the lower-level node, that is, the first node delays transmission of the target information element by means of the delayed transmission threshold, such that an upper-level node in a switched network system relieves sorting pressure on a lower-level node, thereby preventing back pressure of the lower-level node from increasing a transmission delay, optimizing sorting resources among nodes of different levels in the switched network system, and improving stability of the switched network system.
