The method includes: receiving a data packet in a first cycle from a second communication apparatus within a first receive window, where the first receive window is determined based on a first moment at which the data packet in the first cycle arrives at the second communication apparatus and validity duration, and the validity duration is a validity time of the data packet in the first cycle; and delivering the data packet in the first cycle to an application layer within the first receive window. According to the method and apparatus in this application, only a data packet that arrives on time is delivered to the application layer, and a late data packet is not delivered to the application layer, thereby meeting a requirement of an industrial control system.
