    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 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.

    Abstract: System and techniques are described which provide a method for time correlated monitoring of nodes in a network. A statistics request message is sent from a centralized control point to a node in a network having a plurality of nodes, wherein the statistics request message contains a centralized control point time stamp tn of when the message was sent. The statistics request message is received at the node which records a node timestamp ta when the message was received in the node. Node statistics are converted to system time at the centralized control point according to a first delta between tn and ta to generate adjusted node statistics. A second delta is determined at the centralized control point which is applied to the adjusted node statistics to provide consistent system time information for feedback or presentation through a network attached user interface.

    Abstract: Systems and techniques are described which improve performance, reliability, and predictability of networks. Geographically diverse network control nodes (NCNs) are provided in an adaptive private network (APN) to provide backup NCN operations in the event of a failure. A primary NCN node in a first geographic location is operated according to a primary state machine at an NCN active state. A client node is operated according to a client state machine. A secondary NCN node in a second geographic location that is geographically remote from the first geographic location is operated according to a secondary state machine at a standby state. The three state machines operating parallel and upon detecting a change in APN state information, the secondary state machine transitions from the standby state to a secondary active NCN state and the secondary NCN node provides APN timing calibration and control to the client node.
