Abstract
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.
Claims20
A method, comprising:
- receiving a first data message at a first node;
- determining a first type of the first data message;
- determining a first traffic priority of the first data message by examining a first tunnel header of the first data message, the first tunnel header comprises a general packet radio service (GPRS) tunneling protocol (GTP) header;
- and
- applying the first traffic priority to the first data message.
A system, comprising:
- an input configured to receive a first data message;
- a processor coupled to the input, the processor being configured to:
- determine a first type of the first data message;
- determine a first traffic priority of the first data message by examining a first tunnel header of the first data message, the first tunnel header comprises a general packet radio service (GPRS) tunneling protocol (GTP) header;
- and
- apply the first traffic priority to the first data message.
A method, comprising:
- receiving a first data message at a first node, the first data message comprising a cellular broadband data message;
- determining a first type of the first data message;
- determining a first traffic priority of the first data message by examining a first tunnel header of the first data message;
- and
- applying the first traffic priority to the first data message.
