Appl. No.:

17/002762

Inventors:

- Redwood Shores CA, US
Christopher Wayne Parsons - Apex NC, US
Wei Huang - Cary NC, US
Cheryl Lynn Adams - Cary NC, US
Paul D. Worley - Newton Grove NC, US

International Classification:

G06F 8/71
H04L 12/24
H04L 12/28
H04L 29/06

Abstract:

A method for managing multiple software defined wide area network (SD-WAN) software versions includes providing a controller that defines an overall configuration for an SD-WAN and that creates configuration registries for individual SD-WAN appliances to implement their respective portions of the overall configuration. The controller generates, in an intermediate configuration language registry format, a first and second configuration registry for first and second SD-WAN appliance that respectively execute first and second versions of SD-WAN software. The controller respectively transmits the first and second configuration registries to the first and second SD-WAN appliances, which use the first and second configuration registries to configure themselves. The first and second SD-WAN appliances negotiate with each other for common SD-WAN features usable to implement configurations specified in the first and second configuration registries.

Abstract:

System and techniques are described which apply a method for automatic database schema migration. An initial database is installed, according to rules that define tables of data, in an adaptive private network (APN) having a centralized management system including a network control node (NCN) coupled through the APN to a plurality of client nodes, wherein the NCN provides timing and control to the client nodes. An update to the initial database is received, wherein the initial database includes a first table of data stored in a first set of columns and the updated database includes a modified first table having a second set of columns that has a different number of columns as compared to the first table is automatically detected. One or more columns from the second set of columns that are different than the first set of columns are updated for data content.

International Classification:

H04L 12/26
H04L 29/06
H04L 12/24

Abstract:

System and techniques are described for time correlated playback of traffic patters between nodes in a network. Node statistics of data transfers between nodes are received in a control point, wherein the node statistics include a time stamp (t) according to time at the control point of when a request statistics message was sent to each node, a node timestamp (t) according to time at each node of when the message was received in the node, and a first delta between tand tthat is used to determine a second delta which adjusts the node statistics. The node statistics adjusted according to the second delta are stored in a statistics database at the control point. A time stepping mechanism is used to repeatedly access the node statistics from the statistics database at a predetermined rate for playback presentation beginning from a specified start time to a specified end time.
