Patent US 10,693,762

A computer implemented method for controlling a software defined network (SDN) is disclosed. The method includes providing one or more client portals configured for facilitating users controlling networked devices, generating configuration data based on input received from users via the client portals, and provising a master SDN controller for managing data flow control on the SDN network. The master SDN controller is operable to route data for the networked devices, generate a plurality of discrete co-controllers each associated with a particular end user with each co-controller having configuration data and routing data for an associated networked device, dispatching the co-controllers to the networked devices associated with the respective end users, installing the co-controllers on the networked devices, and registering the installed co-controllers with the master SDN controller for controlling the routing of data and configuration of the networked devices.
