Bi-level addressing for internet protocol broadband access
First Claim
1. A method for routing data packets from a subscriber device, over a broadband access link, through a first Internet protocol (IP) version 6 (IPv6) network to a second IP network, the first and second IP networks interfacing through a second IP network edge device, the method comprising:
- providing a first IP address to the subscriber device, the first IP address associated with the first IP network;
providing a second IP address to the subscriber device based on a request routed through the first IP network from the subscriber device, the second IP address being associated with the second IP network; and
addressing data packets from the subscriber'"'"'s device with the first IP address and the second IP address.

Abstract
Data packets of a subscriber are addressed for transmission from an originating device through an IP network to a destination network. A DHCP request, associated with a first subscriber IP address from the IP network, is received from the originating device and routed through the IP network to a destination device in the destination network using an IP network address of the destination device. The destination device forwards the DHCP request to a DHCP server. A DHCP response is received from the DHCP server, through the destination device, including a second subscriber IP address associated with the destination network. The DHCP response is sent through the IP network to the originating device using the first subscriber IP address. The originating device obtains the second subscriber IP address from the DHCP response and addresses data packets using the first and second subscriber IP addresses.

8. A method for addressing data packets of a subscriber for transmission from an originating device over a broadband access link through an Internet protocol (IP) network to a destination network, the method comprising:
-
allocating a first subscriber IP address to the originating device, the first subscriber IP address being associated with the IP network;
receiving a dynamic host configuration protocol (DHCP) request from the originating device, the DHCP request being associated with the first subscriber IP address;
sending the DHCP request through the IP network to a destination device in the destination network using an IP network address of the destination device, the destination device forwarding the DHCP request to a DHCP server;
receiving a DHCP response from the DHCP server, through the destination device, the DHCP response including a second subscriber IP address from the DHCP server, the second subscriber IP address being associated with the destination network; and
sending the DHCP response through the IP network to the originating device using the first subscriber IP address, enabling the originating device to obtain the second subscriber IP address from the DHCP response and address subsequent data packets using the first subscriber IP address and the second subscriber IP address. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A system for addressing data packets of a subscriber for transmission over a broadband access link from an originating device through a first Internet protocol (IP) network to a second IP network, the first IP network and the second IP network interfacing through at least one edge device of the second IP network, the system comprising:
-
a first dynamic host configuration protocol (DHCP) server in the first IP network that allocates a first subscriber IP address to the originating device, the first subscriber IP address being associated with the first IP network; and
a second DHCP server in the second IP network that receives a DHCP request from the originating device through the at least one edge device, allocates a second subscriber IP address to the originating device, and sends a DHCP response having the second subscriber IP address through the at least one edge device to the originating device, the second subscriber IP address being associated with the second IP network;
wherein the originating device addresses data packets using the first subscriber IP address and the second subscriber IP address. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
