Abstract: Systems and methods are provided for receiving bandwidth metrics from a plurality of routers on respective link routes in a network, compiling a link database including the bandwidth metrics of each respective link route in the network, selecting a first designated link path from the link database between a first router and a second router based on an application routing policy, the application routing policy being based on a routing metric, providing a first multiprotocol label switching label based on the first designated link path to the first router of the plurality of routers in the network, and restricting network traffic of the first router to the first designated link path provided in the first multiprotocol label switching label.

Abstract: In one embodiment, a method includes providing a first profile to a plurality of edge routers of the SD-WAN, the plurality of edge routers operable to interface a plurality of devices to the SD-WAN. The first profile enables the plurality of edge routers to discover which devices of the plurality of devices support a first application The method includes receiving, from one or more of the edge routers, information indicating which devices of the plurality of devices support the first application and building a first application fabric based on the information indicating which devices of the plurality of devices support the first application.

Abstract: Techniques for extending application-aware routing (AAR) policies to enable intelligent routing decisions based on device security posture. The techniques may include receiving, from a client device, traffic that is to be sent over a network to an application and determining a security score associated with the traffic. The security score may be based on a security posture associated with the client device, a security level associated with a connectivity network used by the client device, and the like. The techniques may also include determining, based at least in part on the security score and based at least in part on an application-aware routing policy, a path for sending the traffic to the application.

Abstract: The present disclosure is directed to a mechanism for optimized application performance in SD-WAN, and includes the steps of receiving initial traffic packets at a first site for transmission to a second site; determining whether a direct tunnel is established between the first site and the second site based on a state of the second site, the state comprising an active state indicating that a direct tunnel is established between the first and second sites or an inactive state indicating that the direct tunnel is not established between the first and second sites; and in response to determining that the direct tunnel is not established, determining that the initial packets satisfy a configured trigger; forwarding the initial packets to the second site via a backup path; establishing the direct tunnel between the first and second sites; and forwarding subsequent traffic packets to the second site via the established direct tunnel.
