  • Patent number: 8607320
    Abstract: A system, which comprises an authorization controller operable for regulating establishment of user sessions over a data network; a processing subsystem operable for monitoring the user sessions and applying a walled garden policy, wherein application of the walled garden policy respectively associates each user in a certain subset of users with a respective walled garden selected from a common plurality of walled gardens; and a database for storing, in association with each said user in the certain subset of users, a respective identifier corresponding to the respectively associated walled garden.

  • Patent number: 7869372
    Abstract: There are disclosed methods and systems for verifying a connection between a subscriber station and a network wherein a gateway resides intermediate the subscriber station and the network. A method may include receiving instructions from a remote verification host. In response to the instructions, a tester may be introduced into the connection. The tester may receive an IP address of the subscriber station. The tester may use the IP address to perform at least one connectivity test between the gateway and the network. The tester may generate an output reporting a result of the at least one connectivity test.

  • Patent number: 7616577
    Abstract: The present invention provides a method and system for connection verification. An embodiment includes a DSL based system, with a tester resident at a central office respective to a DSLAM. When a problem is encountered by a subscriber, the tester can be readily connected to the DSLAM to allow performance of tests on the connection between the tester, the DSLAM and the Internet. If such tests are successful, then service provider can eliminate that portion of the link as the source of the connectivity problem. If unsuccessful, the service provider can repair that portion of the connection, and thereby potentially obviate the need to send a technician to the subscriber premises.

  • Patent number: 7502327
    Abstract: A novel method and system for testing network connections is provided. In an embodiment, the system includes a network, such as the Internet, which is connected to subscriber devices in a subscriber site via an service provider, a gateway in a telephone company central office, and a DSLAM in an open plant interface. The system also includes a test apparatus operable to inject itself in the connection between the subscriber devices and the Internet at the gateway. The test apparatus can mimic the service provider and, thereby connect directly with the device at the subscriber site and try to test network connections for issue between the service provider and the device. The test apparatus can also mimic the customer and, thereby connect directly with the device and the test network connections between the service provider and the device.

  • Publication number: 20090003221
    Abstract: According to embodiments of the present invention an apparatus suitable for testing a connection defined between a customer entity and a network entity, the connection traversing at least a first portion of a packet-enabled network between said apparatus and the network entity is provided. The apparatus comprises a first interface adapted to exchange with the network entity data associated with the connection over a first traffic VLAN and a second interface adapted to exchange with the customer entity data associated with the connection over a second traffic VLAN bridged to the first traffic VLAN by a bridging entity. The apparatus further comprises a third interface adapted to exchange with a management entity data associated with a management connection over a management VLAN.
