1. A communication method, comprising:
receiving, by a user plane function (UPF), a first packet of a first data stream from a first user equipment (UE), wherein a transmit end of packets of the first data stream is the first UE, and a receive end of packets of the first data stream is a second UE; and
sending, by the UPF, the first packet to the second user equipment at a first moment, wherein:
the first moment is associated with a third moment, a first duration, and a second duration, the third moment is a moment at which the first packet arrives at an ingress port of the first UE, the first duration is a residence time of the first packet on the first UE and a device side time sensitive network (TSN) translator, and the second duration is a packet delay budget corresponding to an uplink protocol data unit (PDU) session of the first packet; or
the first moment is associated with a fourth moment and the second duration, and the fourth moment is a moment at which the first packet arrives at an egress port of the first UE.
