Patent number: 10374814Abstract: Access point cloud controller auto-discovery is provided. An access point, in communication with other access points, receives data indicative of whether each of other access points are managed using a cloud controller or a local controller. When the data is indicative that at least one of the other access points is managed using the cloud controller, the access point is configured to be cloud-controller-managed. When the data is indicative that none of the other access points is managed using the cloud controller, and when the data is further indicative that at least one of the other access points is managed using the local controller, the access point is configured to be local-controller-managed.Type: GrantFiled: July 26, 2016Date of Patent: August 6, 2019Assignee: EXTREME NETWORKS, INC.Inventors: Rajeev Kumar Mishra, Senthilraj Shanmugavadivel, Dominic Velikakath Peter, Jeelan Basha Poola

Patent number: 8934867Abstract: An on-demand access tunnel to a service provider is provided for a mobile device that first receives information about supported service providers from a wireless communication network entity. The mobile device can select a supported service provider and start an association process to communicate with the selected service provider. The network entity determines the selected service provider and sets up a tunnel connection from an access point of the wireless communication network to the selected service provider. The tunnel connection is torn down when the mobile device dissociates from the access point and no other device is connected to the service provider network using the tunnel connection.Type: GrantFiled: July 10, 2012Date of Patent: January 13, 2015Assignee: Symbol Technologies, Inc.Inventors: Senthilraj Shanmugavadivel, Anil Kaushik, Raj Kiran
