A solution for establishing a data traffic (e.g., PDU) session for a user equipment (UE) on a network (e.g., 5G cellular network) comprises receiving, by a session management node, a request for the data traffic session for the UE; determining a requested traffic type for the data traffic session, wherein the requested traffic type comprises a first traffic type or a second traffic type; determining whether the session management node is connected to a first user plane function that can support the requested traffic type; based at least on determining that the first user plane function cannot support the requested traffic type, connecting, by the session management node, to a second user plane function that can support the requested traffic type; and based at least on connecting to the second user plane function, establishing the requested data traffic session for the UE using the second user plane function.
