摘要： Systems and techniques, including special messages and state machines, are described that configures an intermediate site to dynamically trigger creation of and removal of a dynamic conduit between two sites based on usage that is tracked at the sites. The intermediate site providing WAN-to-WAN forwarding between the two sites, monitors throughput statistics on each local WAN link (LWL) associated with the two sites. If traffic between the two sites passes a configured first threshold or if LWL usage passes a configured second threshold, the intermediate site sends a message to the two sites to set up a dynamic conduit directly coupling the two sites. Busy lists are used to keep track of eligible site pairs. Once a dynamic conduit is set up between two sites, a grow technique tests the dynamic conduit increasing communication flows between the two sites each configured sampling period before putting the conduit in normal use.

摘要： Systems and techniques are described for a centralized management system operating within a virtual machine which configures, monitors, analyzes, and manages an adaptive private network (APN) to provide a discovery process that learns about changes to the APN through a network control node (NCN) that is a single point of control of the APN. The discovery process automatically learns a new topology of the network without relying on configuration information of nodes in the APN. Network statistics are based on a timeline of network operations that a user selected to review. Such discovery and timeline review is separate from stored configuration information. If there was a network change, the changes either show up or not show up in the discovery process based on the selected time line. Configuration changes can be made from the APN VM system by loading the latest configuration on the APN under control of the NCN.

摘要： 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 includes 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.
