Abstract: Techniques are described to automatically activate and deactivate standby backup paths in response to changing bandwidth requirements in an adaptive private network (APN). The APN is configured with one or more regular active wide area network (WAN) links in an active mode and an on-demand WAN link in a standby mode. The on-demand WAN link is activated to supplement the conduit bandwidth when an available bandwidth of the conduit falls below a pre-specified trigger bandwidth threshold and the conduit bandwidth usage exceeds a usage threshold of a bandwidth of the conduit that is being supplied by the active paths (BWC). The on-demand WAN link is deactivated to standby mode when an available bandwidth of the conduit is above the pre-specified trigger bandwidth threshold and the conduit bandwidth usage drops below the usage threshold of BWC. Techniques for adaptive and active bandwidth testing of WAN links in an APN are also described.

Abstract: Techniques for providing a backup network path using a standby wide area network (WAN) link with reducing monitoring. Packet loss and latency metrics are monitored for network paths in an adaptive private network (APN) connecting a first user and a second user according to control traffic operating at a first control bandwidth for each network path. A determination is made that a first network path uses a standby WAN link, has packet loss and latency metrics indicative of a good quality state, and has at least one characteristic that identifies the first network path as a backup network path. The control traffic is then reduced for the backup network path to a second control bandwidth substantially less than the first control bandwidth. The backup network path is made active when the number of active network paths is less than or equal to a minimum number.
