Adaptive private network with geographically redundant network control nodes

A method to provide geographically diverse network control nodes (NCNs) in an adaptive private network (APN), the method comprising:

• operating a first node, a primary NCN, in a first geographic location according to a primary state machine at an NCN active state;
• operating in parallel a second node, a first client node, according to a first client state machine at a first client primary active state and a third node, a second client node, according to a second client state machine at a second client primary active state;
• and
• operating a fourth node as a client or as a secondary NCN, the fourth node located in a second geographic location that is geographically remote from the first geographic location, the fourth node operating as a client according to a secondary state machine at a client active and secondary standby NCN state, wherein upon detecting a change in APN state information, the primary NCN provides APN timing calibration and control to the first client node and the fourth node transitions to a secondary active NCN state, the second client node transitions to a second client secondary active NCN state, and the fourth node operating as the secondary NCN provides APN timing calibration and control to the second client node.

• operating a fourth node as a client or as a secondary NCN, the fourth node located in a second geographic location that is geographically remote from the first geographic location, the fourth node operating as a client according to a secondary state machine at a client active and secondary standby NCN state, wherein the first client node is coupled by a first conduit to the primary NCN node and by a second conduit to the fourth node, the second client node is coupled by a third conduit to the primary NCN and by a fourth conduit to the fourth node, and the primary NCN is coupled by a fifth conduit to the fourth node and wherein upon detecting a change in operating state for one or more of the conduits coupled to the primary NCN, the fourth node transitions to a secondary active NCN state.

A computer readable non-transitory medium storing a computer program which causes a computer system to perform a method to provide geographically diverse network control nodes (NCNs) in an adaptive private network (APN), the method comprising:

• operating a first node, a primary NCN, in a first geographic location according to a primary state machine at an NCN active state;
• operating a second node, a client node, according to a client state machine;
• and
• operating a third node as a client or as a secondary NCN, the third node located in a second geographic location that is geographically remote from the first geographic location, the third node operating as a client according to a secondary state machine at a client active and secondary standby NCN state, wherein upon detecting a change in APN state information, the secondary state machine transitions from the client active and secondary standby NCN state to a secondary active NCN state and the third node operating as the secondary NCN provides APN timing calibration and control to the client node.
