Abstract: An approach is provided for determining if video content provided to a device is still being viewed, without disrupting the presentation of the content. A device is monitored for input from the user, wherein the device is configured to present content to the user. A determination is made whether the user input is within a predetermined time period. A control signal is generated to change the presentation of the content without explicitly notifying the user of the change, wherein the presentation of content will cease if the user input is not within the predetermined period.

Further, the system and method may transmit, to one or more network elements, the test data traffic. Even further, the system and method may receive, from the management system, a query associated with the management protocol that requests data traffic information associated with at least one of the generated test data traffic, transmitted test data traffic, and received test data traffic. The system and method may transmit, to the management system, the requested data traffic information in response to the query.

The system and method may also include one or more processors at the session border controller (SBC) configured to identify an identifier associated with the network element, wherein the identifier corresponds to a second source information, and to replace the first source information in the message received from the network element with the second source information corresponding to the identifier of the network element. The system and method may also include one or more databases configured to store the second source information. The system and method may also include a transmitter at the session border controller (SBC) configured to transmit the message with the second source information to a service provider proxy for granting network access.

Abstract: A method that includes establishing a connection with a default access point, transmitting a request to access or utilize an application, a service, or a resource, receiving a response to the request that includes a location of a serving access point that provides the application, the service, or the resource, establishing a connection with the serving access point, and receiving an assignment of a network address that is anchored by the serving access point.

Abstract: A master network interface device (M-NID) receives, from a network management system (NMS) via a first peer-to-peer (P2P) transport channel, first data destined for a first client network interface device (C-NID), where the first data is associated with network management functions. The M-NID further receives, from the NMS via the first P2P transport channel, second data destined for a second C-NID, where the second data is associated with network management functions. The M-NID forwards the first data from the M-NID to the destination first C-NID via a second P2P transport channel that is different than the first P2P transport channel. The M-NID also forwards the second data from the M-NID to the destination second C-NID via a third P2P transport channel that is different than the first P2P transport channel.
