US Patent 11943146 Traffic prioritization in SD-WAN

Some embodiments provide a method, 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 is established by a set of edge nodes and a set of gateways. At a particular edge node of the SD-WAN, the method identifies 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, the method examines a set of header fields within the tunnel header to identify a specified traffic priority applicable to the 5G message. The method applies the identified traffic priority within the SD-WAN.
