Abstract:
1. A method comprising: receiving, at a controller apparatus in a first mobility sub-domain of a network comprising a plurality of mobility sub-domains, from a first access switch in the first mobility sub-domain a request message containing a request for guest network access for a device; forwarding, at the controller apparatus, the request message to a guest controller that is configured to support guest network access for devices that are not authorized for native access to the network; receiving, at the controller apparatus, a response message from the guest controller, the response message containing information to enable guest access for the device; and establishing, at a tunneling endpoint apparatus in the first mobility sub-domain, a tunnel to the guest controller so that traffic for the device travels in a tunnel between the first access switch and the tunneling endpoint apparatus, through the tunneling endpoint apparatus in the first mobility sub-domain and in the tunnel between the tunneling endpoint apparatus in the first mobility sub-domain and the guest controller.
