Abstract: Some embodiments provide a method for implementing context-aware routing for a software-defined wide-area network (SD-WAN). The method is performed at a particular SD-WAN edge forwarding element (FE) connected to a particular cloud datacenter. The method receives a message specifying a weight for a virtual network address associated with a set of application resources distributed across multiple cloud datacenters including the particular cloud datacenter. The method converts the specified weight into a route weight for the SD-WAN. The method provides the converted route weight to a set of SD-WAN edge FEs connected to a set of branch networks, and each SD-WAN edge FE in the set of SD-WAN edge FEs uses the provided route weight to calculate a total cost for routing data messages directed to the virtual network address to the particular cloud datacenter.

Abstract: Some embodiments provide a method of implementing context-aware routing for a software-defined wide-area network, at an SD-WAN edge forwarding element (FE) located at a branch network connected to the SD-WAN. The method receives, from an SD-WAN controller, geolocation route weights for each of multiple cloud datacenters across which a set of application resources is distributed. The application resources are all reachable at a same virtual network address. For each of the cloud datacenters, the method installs a route for the virtual network address between the branch network and the cloud datacenter. The routes have different total costs based at least in part on the geolocation metrics received from the SD-WAN controller. The SD-WAN edge FE selects between the routes to establish connections to the set of application resources.
