1. For a software-defined wide area network (SD-WAN) that handles (i) traffic for a 5G network and (ii) traffic outside of the 5G network, the SD-WAN established by a set of edge nodes and a set of gateways, a method comprising:
at a particular edge node of the SD-WAN:
identifying whether a received data message is a 5G message that includes a tunnel header of a particular type associated with the 5G network;
when the data message is a 5G message, examining a set of header fields within the tunnel header to identify a specified traffic priority applicable to the 5G message; and
applying the identified traffic priority within the SD-WAN.
