Abstract: A method and system are configured to infer one or more virtual private network (VPN) services within a physical network. Topologically relevant network information is received for the physical network with regard to nodes, interfaces, connections, and protocols, and the existence of each virtual private network service is inferred based on the stored network topology information. Network objects are also inferred, including routed paths, label switched paths, Internet Protocol Security (IPSec) tunnels, and Layer Two Tunneling Protocol (L2TP) tunnels.

Abstract: Systems and methods are disclosed for managing services on a network. In one exemplary embodiment, the method includes receiving topologically relevant network information concerning nodes, interfaces, connections and/or protocols; resolving conflicts in the received information; determining and storing a network topology from the received and resolved information; and inferring one or more services based on the stored topology.

Abstract: In accordance with one aspect of the invention, a method of receiving content over a content delivery system is provided. The method includes receiving a user request to initiate a rewind operation on content locally available in a live-off-disk (LOD) buffer. The content is associated with an event received over a content delivery system. If all of the event is not available in the LOD buffer, a message is communicated over the content delivery system to a headend requesting remaining content associated with an unreceived portion of the event. In response to the message, the remaining content is received from the headend over the content delivery system.
