  • Patent number: 9112879
    Abstract: A system and method for network authentication is provided. A network access device is operable to establish a communications with an internal network. A client device is operable to request and establish the communications over the internal network by interfacing with the network access device. A processor is operable to interface with the network access device to establish the communications between the client device and the internal network. The processor is also operable to establish a communications level for the communications based on the location of the client device.

  • Patent number: 8463880
    Abstract: Systems and methods of removing a tunnel created when a client having an active IP session with a first portal point in a first subnet of a network, disconnects from the first portal point and reconnects to a second portal point in a second subnet of the network, the client maintaining an IP address assigned to it by the first subnet, embodiments of the method including the steps of determining whether data is scheduled to transfer from the second portal point to the client; if no data is scheduled, disconnecting the client from the second portal point; deactivating the IP session, whereby the IP address is released to the first subnet; removing the tunnel; reconnecting the client to the second portal point; and activating a second IP session between the client and the second portal point, whereby a second IP address is assigned to the client by the second subnet.

  • Patent number: 7869374
    Abstract: A system and methods of detecting a loop in a network having at least one access point with a first interface and a second interface, at least one switch with multiple ports, and at least one client with a first interface and a second interface, including: the access point first interface intermittently transmitting a loop check packet to the switch; the switch receiving the loop check packet at one of the ports and transmitting the loop check packet to the client through another one of the ports; the client first interface receiving the loop check packet; the client second interface retransmitting the loop check packet to the access point; and the access point second interface being configured to receive the retransmitted loop check packet. The access point detects a loop when the access point second interface receives the retransmitted loop check packet. Other embodiments eliminate the loops in various ways.
