Abstract
The present invention provides methods and systems to remove the dependence on the IP layer (OSI layer three) in Video-on-Demand (VoD) transport networks. The present invention replaces the IP layer with Ethernet layer two addressing and even layer one, allowing connectivity in access/aggregation networks without IP layer three capabilities. The present invention enables STBs to communicate with VoD controllers, servers, and the like at layer two and/or layer one, eliminating the need for layer three routing capabilities in access/aggregation networks.
