Abstract: An information transmission method and an apparatus, where the method includes: determining, by an application function network element, an association relationship of a port pair corresponding to a protocol data unit (PDU) session; determining delay information of the port pair; and sending port pair information to a time sensitive networking (TSN) system, where the port pair information includes the association relationship of the port pair and the delay information of the port pair. In the embodiments of this application, attribute information of a virtual switching node can be obtained and reported in a 5th generation (5G) system, such that a TSN system plans a transmission path of a TSN flow on the virtual switching node and a network resource for the transmission path.
