Abstract: Embodiments of this application disclose a communication method, and may be applied to a scenario such as switch networking (for example, high-performance computing HPC), the industrial Ethernet, or the like. The method includes: receiving first information sent by a second device, where the first information indicates a second MAC frame length supported by the second device; determining a third MAC frame length based on a first media access control MAC frame length and the second MAC frame length, where the first MAC frame length is a MAC frame length supported by the first device, and the first MAC frame length is the same as or different from the second MAC frame length; and communicating with the second device based on the third MAC frame length.

Abstract: This application provides a collective communication method and a communication apparatus. The method includes: A first terminal device receives at least one second packet from a first network device, where the second packet includes information about a first process and information about a network device corresponding to the first process, the first process is used to execute a first task, and the information about the network device corresponding to the first process is information about a network device to which a terminal device including the first process belongs. The first terminal device determines a third packet based on the at least one second packet, where the third packet includes information about a target network device and information about all first processes that correspond to the target network device and that execute the first task.
