Abstract: Embodiments of this application provide a period mapping method and a network device. The method includes: receiving, by a downstream first network device, first information sent by an upstream second network device, where the first information carries a number of the 1st period of the second network device, the number is referred to as a first number, and the first number includes a first label number and a first group number; and establishing, by the first network device, mapping relationships between numbers of a plurality of periods of the first network device and numbers of a plurality of periods of the second network device based on a mapping relationship between a second label number and a second group number that are included in a number of a first period that can be used to send the first information and a first label number and a first group number.

Abstract: A communication method and apparatus are provided for transmitting packets of a data stream between user equipment. After receiving a first packet from a first user equipment, a user plane function (UPF) forwards the first packet to a second user equipment at a first moment, so that the first packet that arrives at the UPF before the first moment is not forwarded to the second user equipment until the first moment, to support deterministic sending and ensure that a time sensitive communication (TSC) packet is sent at a determined moment, so as to provide deterministic delay assurance for applications such as industrial control and telemedicine.
