Systems and methods for selecting tunnels for transmitting application traffic by an SD-WAN application include a software-defined wide area network (SD-WAN) application executing on a client device establishing a connection between the SD-WAN application and one or more applications. The SD-WAN application maintains a plurality of tunnels between the SD-WAN application and respective tunnel destinations. The SD-WAN application receives application traffic from an application of the one or more applications. The SD-WAN application selects, based on the application traffic, a respective tunnel of the plurality of tunnels via which to transmit the application traffic of the application. The SD-WAN application transmits the application traffic via the selected tunnel.
