Abstract
The present application relates to communications between a partner network and a wide area network (WAN) via the Internet. The WAN advertises unicast border gateway protocol (BGP) address prefixes for a plurality of front-end devices in the WAN. An agent in the partner network measures a plurality of paths to a service within the WAN. Each of the plurality of paths is associated with one of the plurality of front-end devices and a respective unicast BGP address prefix. The agent provides measurements of the plurality of paths to the WAN. The WAN selects a path within the WAN for the service. The agent receives a routing rule specifying a unicast address prefix for a selected device of the plurality of front-end devices of the WAN. The agent forwards data packets for the service to the respective border gateway protocol address prefix of the selected device via the Internet.
