1. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and computer program code being configured, with the at least one processor, to cause the apparatus to perform:
receiving one or more forwarding tables from a centralized network configuration entity of a time sensitive network, wherein the forwarding tables comprise entry information, wherein the time sensitive network comprises a time sensitive network bridge, the time sensitive network bridge comprising at least one ingress network port and at least one egress network port, and wherein the entry information comprises a destination medium access control address to which filtering information of an entry applies, and a corresponding ingress port and egress port pair;
determining, based at least in part on the one or more forwarding tables, rules for mapping at least one uplink data stream of the time sensitive network to at least one of: a protocol data unit session and a quality of service flow, wherein determining the rules for mapping comprises:
determining, using the entry information, a protocol data unit session configured to map the uplink data stream, and
determining a quality of service flow to map the uplink data stream to by using the entry information and at least one priority code point value received in at least one header of at least one data stream; and
determining to insert or remove an uplink classifier and/or branching point for a protocol data unit session based at least in part on the entry information of the one or more forwarding tables,
wherein the insertion or removal of the uplink classifier and/or the branching point causes network traffic at the user equipment to be forwarded via one or more user plane functions that are not visible to the time sensitive network.
