SD-WAN TRAFFIC ENGINEERING

Abstract

A method implemented by a first edge node of a software-defined wide area network (SD-WAN) for steering traffic over an SD-WAN path. The first edge node receives, on a control plane, first gateway (GW) properties of a first adjacent SD-WAN gateway of a second edge node of the SD-WAN, wherein the first edge node is an authorized peer of the second edge node, and the first adjacent SD-WAN gateway satisfies a first policy of the second edge node. The first edge node generates, based on the first GW properties, a data packet containing header information for steering the data packet to the second edge node over an SD-WAN path comprising the first adjacent SD-WAN gateway. The first edge node transmits, on a data plane, the data packet to a next hop along the SD-WAN path as indicated by an outer Internet Protocol (IP) destination address of the data packet.
