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.

Abstract: A routing system coupled to a label switching network receives a pool of network addresses allocated to a mobility region in the network, where the pool of network addresses includes a sequence of contiguous network addresses. The routing system stores the pool of network addresses, and allocates a range of mobility labels to the network address pool for use in communicating with mobile nodes in the mobility region.

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.
