Claim Text:
1. A method of delegating prefixes comprising: determining a home network having a data gateway configured to facilitate Internet signaling with an Internet service provider (ISP) network, the Internet signaling requiring data addresses derived from a data Internet protocol (IP) prefix provided to the data gateway from an ISP delegator; determining the home network having a video gateway configured to facilitate video signaling with a video network, the video signaling requiring video addresses derived from a video IP prefix provided to the video gateway from an video delegator; determining the home network having customer premise equipment (CPE) operating according to a plurality of restrictions, the restrictions including: (a) the CPE being prevented from being delegated data and/or video addresses directly from more than one of the data gateway and the video gateway and (b) the CPE being required to use the video addresses for the video signaling and the data addresses for data signaling; (c) translation of video addresses used for video signaling being prohibited; and (d) video signaling with the CPE being required to pass between the video network and the CPE through the video gateway; identifying the video IP prefix provided to the video gateway from information included within a routing delegation message transmitted from the video gateway to the data gateway; deriving the data and video addresses for the CPE at the data gateway using the data IP prefix provided thereto from the ISP delegator and the video IP prefix provided thereto from the video gateway within the routing delegation message, including deriving the data and video addresses such that each CPE is associated with a different one of the data addresses and a different one of the video addresses; delegating with the data gateway the data and video addresses derived for each CPE to the corresponding CPE through communications carried over a common link, the common link being sufficient to facilitate direct communications between each of the data gateway, the video gateway and the CPE; generating a routing table sufficient for use at the data gateway to route Internet signaling carried over the common link having one of the data addresses associated with the CPE to the ISP network and to route video signaling carried over the common link having one of the video addresses associated with the CPE to the video gateway such that the video gateway thereafter routes the video signaling to the video network; simultaneously routing the Internet and video signaling associated with one of the data addresses and the video addresses delegated to the CPE through the gateway, the gateway interfacing the corresponding Internet signaling with the ISP network through a first interface and the corresponding video signaling with the video gateway through a second interface; and interfacing through the first interface using a wireline interface and the second interface using a wireless interface sufficient for communicating over the common link with the video gateway.
