Abstract
An improved network router apparatus and associated network architecture is disclosed. In one exemplary embodiment, the router apparatus is adapted to interface between an external network (such as an HFC/DOCSIS digital network) and a local network created using existing HFC cabling within a premises. The router device provides address translation between the single IP address assigned to the router by the external network and the addresses of the individual nodes or access points on the local network through creation of logical ports assigned to various portions of the available bandwidth of the cable system. The router further distinguishes network protocols from the media content streamed over the HFC network, allowing for the foregoing functionality and replacing any existing cable modem. Methods of initiating the router and assigning addresses are also disclosed, as well as business models for leasing the router equipment and access points.
