Abstract
Various implementations described herein relate to routing network data traffic using network tunnels. In some implementations, one or more tunnels are established between a remote gateway device and a central gateway system. The central gateway system receives data traffic-to-tunnel information from the remote gateway device, and the central gateway system incorporates the data traffic-to-tunnel information in a data traffic-to-tunnel mapping. The data traffic-to-tunnel information comprises n-tuple of network flow information, network flow tags, application-to-tunnel binding information, or the like. The central gateway system receives first data traffic from the remote gateway and forwards the first data traffic to a server. Subsequently, the central gateway system receives second data traffic and forwards the first data traffic to the remote gateway device over one or more select tunnels selected from the established tunnels. The select tunnels can be selected based on based at least in part on the data traffic-to-tunnel mapping.
