Abstract: A device communicates with feature peers, associated with a network, to obtain information associated with the feature peers, and receives a customer packet. The device also determines, based on the feature peer information, which of the feature peers support a feature associated with the customer packet, and selects, from the determined feature peers, a set of feature peers for the customer packet to traverse. The device further associates, with the customer packet, an additional packet used for delivering the feature associated with the customer packet, and forwards the customer packet and the additional packet to one of the feature peers in the selected set of feature peers.

Abstract: A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames.

Abstract: System and method for providing a termination point for service emulation instances in an access network is provided. In an embodiment, the service emulation instances are implemented utilizing, for example, pseudowires. Communications to and from the access network are aggregated and transmitted via one or more pseudowires to a service emulation instance terminator. The service emulation instance terminator converts the traffic to its native form and, if necessary, converts the traffic to a different type of format or service. The service emulation instance terminator then frames the traffic for the appropriate type of service and transmits the traffic to the service edge. Traffic received from the service is removed prepended with a pseudowire label and aggregated with other traffic. The aggregated traffic is transmitted to the customer via the access network. If necessary, an interworking function may convert the traffic from one type of service to another type of service.

Abstract: One or more devices, in a video content delivery network, store video content for one or more customer premise devices in a hierarchical storage, and provide real time video content from the hierarchical storage, via multicast or unicast, to the one or more customer premise devices. The one or more devices also provide non-real time video content from the hierarchical storage to the one or more customer premise devices during idle time periods associated with the network. The one or more devices further establish a license with the one or more customer premise devices to view video content in multiple formats, and establish a license with the one or more customer premise devices to view video content via multiple customer premise devices.

Abstract: A computing device, in a video content delivery network, intercepts requested video content prior to delivery of the requested video content to a customer premise device of the network, and receives subscription and authentication information of a customer associated with the customer premise device. The computing device receives video content provider information, and validates the requested video content based on the subscription and authentication information and the video content provider information. The computing device receives capability information associated with the customer premise device, and receives bandwidth information associated with the network. The computing device determines a quality of video content, to provide to the customer premise device, based on the customer premise device capability information and the network bandwidth information, and provides, to the customer premise device, video content with the determined quality.

Abstract: One or more devices, in a video content delivery network, provide real time video content to one or more devices located at a customer premise. The one or more devices also provide non-real time video content to at least one of the customer premise devices during idle time periods associated with the network and using lower effort Internet protocol (IP) transport. The non-real time video content may be broadcast, at a time after the idle time periods, by at least one of the customer premise devices.

Abstract: A device communicates with feature peers, associated with a network, to obtain information associated with the feature peers, and receives a customer packet. The device also determines, based on the feature peer information, which of the feature peers support a feature associated with the customer packet, and selects, from the determined feature peers, a set of feature peers for the customer packet to traverse. The device further associates, with the customer packet, an additional packet used for delivering the feature associated with the customer packet, and forwards the customer packet and the additional packet to one of the feature peers in the selected set of feature peers.

Abstract: A device receives, from feature peers associated with a network, information associated with the feature peers, receives a customer packet, and determines, based on the feature peer information, which of the feature peers support a feature associated with the customer packet. The device also selects, from the determined feature peers, a set of feature peers for the customer packet to traverse, attaches a feature header to the customer packet to create a modified customer packet, and forwards, based on the feature header, the modified customer packet to one of the feature peers in the selected set of feature peers.

Abstract: A device communicates with feature peers, associated with a network, to obtain information associated with the feature peers, and receives a customer packet. The device also determines, based on the feature peer information, which of the feature peers support a feature associated with the customer packet, and determines service providers associated with the determined feature peers. The device further selects, from the determined feature peers, a set of feature peers for the customer packet to traverse when the service providers associated with the determined feature peers are also associated with the device. The device then provides a tunnel header and a feature header in the customer packet to create a modified customer packet, and forwards, based on the tunnel and feature headers, the modified customer packet to one of the feature peers in the selected set of feature peers.

Abstract: A device communicates with feature peers, associated with a network, to obtain information associated with the feature peers, and receives a customer packet that includes a feature header. The device also modifies, based on the feature peer information, current condition state signaling, and other information, the feature header to create a modified customer packet, and determines, based on the feature peer information, the current condition state signaling, and the other information, which of the feature peers support a feature associated with the modified customer packet.

Abstract: In one embodiment of the invention, a network system includes a boundary router, a second router, and an upstream link of the second router coupled between to the output port of the boundary router and an input port of the second router. The second router includes an admission control function and a data plane. In response to a request to reserve resources for a flow through the second router, the admission control function performs admission control for both the upstream link and its downstream link. In a preferred embodiment, the second router performs admission control for the upstream link only if the second router is a receiving edge router for the flow. Because the second router performs admission control for its upstream link, the boundary router transmits the request toward an upstream router without performing admission control for the link.

Abstract: A network architecture in accordance with the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs). The communication network includes a plurality of boundary routers that are connected by access links to CPE edge routers belonging to the one or more VPNs. To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS provided to traffic from within the customer's VPN, the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN traffic.
