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.

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: One method occurs at a first network node in a service provider network for providing at least one service to multiple tenants. The method includes generating, using input from an administrator of the service provider network, user configuration information for a first tenant; sending, to the first tenant, at least some of the user configuration information; receiving, from the first tenant, first configuration information for configuring a first conduit for tunneling communications between the service provider network and a first site associated with the first tenant's SD-WAN; configuring, using the first configuration information, the first conduit, wherein the first network node is associated with a plurality of conduits, wherein a second conduit of the plurality of conduits is at least in part configured by a second tenant and not the first tenant; and tunneling, via the first conduit, communications between the service provider network and the first site.
