Abstract: Systems and methods for provisioning and validating a network are disclosed. One method can comprise providing a first communication tunnel between a network access point and a first tunnel endpoint. Availability of the first tunnel endpoint can be determined. If the first tunnel endpoint is determined to be available, network traffic can be routed to the first tunnel endpoint. If the first tunnel endpoint is determined to be unavailable, a second communication tunnel between the network access point and a second tunnel endpoint can be provided.

Abstract: A forecast model processes performance data from a site, e.g., a cable modem termination system (CMTS), to obtain a set of concurrency equations for existing speed tiers that is based on an observed subscriber bandwidth for the site. A new set of concurrency equations is obtained for new speed tiers so that a new subscriber bandwidth can be predicted for the new speed tiers. Based on the new subscriber bandwidth, expected subscriber growth, and changes in data consumption, the site is reconfigured with additional ports based on the forecast. This process can be repeated for the other sites. Sites may be grouped together based on the observed subscriber bandwidth. A new subscriber bandwidth may be predicted for the group with the new speed tiers so that additional ports can be configured for each of the sites in the group.

Abstract: Content may be received at an edge location in one format, but delivered to a terminal on an access network in another format. The received content may be transcoded at the edge location. The transcoded content may be stored, or immediately delivered. The transcoded content may be fragmented prior to storage. Multiple copies of the transcoded content may be maintained in multiple formats. These formats may be aligned with one another such that delivery of the content can include delivering portions of the content in one format and other portions of the content in another format.

Abstract: Computing devices, computer-readable media storing computer-executable instructions, methods, and systems for discovering, organizing, and presenting supplemental content are disclosed. A discovery system may be used to discover an item, such as a supplemental content presentation application, which, when launched may present supplemental content to a user while the user is consuming primary content. The supplemental content presentation application may also present a timeline that users may interact with to view different portions of the supplemental content. The timeline may also be modified by adding markers along the timeline so that when a marker is selected, a particular piece of supplemental content is presented.

Abstract: Methods and systems are provided for routing or forwarding packet data conforming to two different communication protocols simultaneously in a computer network. The first protocol may be a legacy protocol, such as IPv4, with routing being performed in a manner that maintains legacy behavior and functions. Such functions may include network address translation. The second protocol may be a newer protocol, such as IPv6, with the routing or forwarding being performed through reduced complexity bridging that enables simplified connectivity of second protocol devices. The bridging performed typically requires less memory and processing power than traditional routing techniques such as those implemented for the first protocol. Reduced memory and processing power requirements enable the second protocol routing functions to be added to legacy equipment that would not otherwise be able to support routing of the second protocol packet data.

Abstract: A subscriber network architecture includes a packet processing node that communicates with a network backbone and with a plurality of access nodes. The access nodes communicate with a plurality of user devices. The packet processing node controls Quality of Service (QoS) levels for the subscriber devices, routes user data to devices via the access nodes and receives data from devices via the access nodes for forwarding across the network backbone.
