Abstract

A system allows first users to connect through an IPv4 web interface to access content (e.g., information and services) of second users who provide the content using IPv6. The second users are effectively mobile web servers. In an implementation, the system is a streaming media network (e.g., lifecasting) where first users are video viewers and second users are streaming video providers. In the system, a second user runs a home agent client (e.g., plug in) that connects to a home agent server using IPv6. The home agent client and server encapsulate and deencapsulate the IPv6 information. Information is transmitted and routed using IPv6 in an IPv4 environment. Any number of second users connect to the first user'"'"'s content via an IPv4 web interface.

Claims

1. A method comprising:

providing a first home agent server, coupled to an Internet Protocol version 4 (IPv4) network, managing Internet Protocol version 6 (IPv6) clients and routing IPv6 information over layer 3;

providing a stream server, coupled to the first home agent server via the IPv4 network;

providing a first IPv6 client, coupled to the first home agent server via the IPv4 network;

from the first IPv6 client, sending information to the first home agent server comprising an IPv4 address, an IPv6 address associated with the first IPv6 client, and when no client is connected to a stream of the first IPv6 client, a binding update message without stream traffic;

implementing a first IPv6-over-IPv4 tunnel in the IPv4 network between the first IPv6 client and first home agent server;

through the first IPv6-over-IPv4 tunnel, transferring information from the first IPv6 client directly to the first home agent server in an encrypted form;

transferring the information from the first home agent server directly to the stream server in an unencrypted form without using the first IPv6-over-IPv4 tunnel;

providing a second home agent server, coupled to an Internet Protocol version 4 (IPv4) network; and

at the first home agent server replicating the information transferred from the first IPv6 client and transmitting the replicated information to the second home agent server.

2. The method of claim 1 comprising:

allowing a plurality of recipient IPv4 client devices to couple to the stream server via the IPv4 network, wherein each of the recipient IPv4 client devices is capable of receiving the information transferred from the first IPv6 client without using the IPv6-over-IPv4 tunnel to the stream server.

3. The method of claim 2 wherein each of the recipient IPv4 client devices cannot view an IPv6 address of the first IPv6 client.

4. The method of claim 2 wherein the first home agent server functions as a proxy for the first IPv6 client.

5. The method of claim 1 wherein the first home agent server is coupled to a IPv6 network and the method comprises:

providing a second IPv6 client, coupled to the first home agent server via the IPv6 network without using a IPv6-over-IPv4 tunnel.

6. The method of claim 1 comprising:

on the first IPv6 client, storing a home agent client executable code, wherein when executed the executable code causes display on a screen of the first IPv6 client a sign-on graphical interface comprising a password input.

7. The method of claim 1 wherein the information transferred from the first IPv6 client comprises a video stream.

8. The method of claim 1 wherein the stream server is a first stream server, and the method comprises:

providing a second stream server, coupled to the second home agent server via the IPv4 network; and

transmitting the replicated information from the second home agent server to the second stream server.

9. The method of claim 1 comprising:

at the first home agent server, decrypting the encrypted information from the first IPv6 client into unencrypted format.

10. The method of claim 1 comprising:

transmitting information streamed to the first home agent transmit video to the second home agent server via an IPv6 network.

11. The method of claim 1 comprising:

providing an IPv6 database comprises a list of IPv6 accounts, wherein information in the IPv6 database is propagated to the first and second home agents via an IPv6 network.

12. The method of claim 1 wherein the information comprises a video stream, and the video stream is streamed in a first format from the first IPv6 client to the first home agent server, the first home agent transcodes the video stream into a second format, and the video stream transcoded in the second format is streamed to the stream server.

13. The method of claim 1 wherein the first IPv6 client comprises a home agent client application executing at the first IPv6 client to assist in implementing the IPv6-over-IPv4 tunnel.

14. A method comprising:

providing a first home agent server, coupled to an Internet Protocol version 4 (IPv4) network, managing Internet Protocol version 6 (IPv6) clients and routing IPv6 data using layer 3;

providing a stream server, coupled to the first home agent server via the IPv4 network;

providing a first IPv6 client, coupled to the first home agent server via the IPv4 network;

from the first IPv6 client, sending to the first home agent server an IPv4 address and IPv6 address associated with the first IPv6 client, and when no receiver is connected to a stream of the first IPv6 client, sending a binding update message without video traffic;

implementing a first IPv6-over-IPv4 tunnel in the IPv4 network between the first IPv6 client and first home agent server;

through the first IPv6-over-IPv4 tunnel, transferring video information from the first IPv6 client directly to the first home agent server in an encrypted form;

transferring the video information from the first home agent server directly to the stream server in an unencrypted form without using the first IPv6-over-IPv4 tunnel;

providing a second home agent server, coupled to an Internet Protocol version 4 (IPv4) network; and

at the first home agent server replicating the video information transferred from the first IPv6 client and transmitting the replicated video information to the second home agent server.

15. The method of claim 14 wherein the video information is streamed in a first format from the first IPv6 client to the first home agent server, the first home agent transcodes the video information into a second format, and the video information, transcoded in the second format, is streamed to the stream server.

16. The method of claim 14 comprising:

a plurality of recipient IPv4 client devices, coupled to the stream server via the IPv4 network, wherein each of the recipient IPv4 client devices is capable of receiving the information transferred from the first IPv6 client without using the IPv6-over-IPv4 tunnel to the stream server.

17. The method of claim 14 comprising:

on the first IPv6 client, storing a home agent client executable code, wherein when executed the executable code assists in implementing the IPv6-over-IPv4 tunnel.

18. The method of claim 14 wherein the stream server is a first stream server, and the method comprises:

providing a second stream server, coupled to the second home agent server via the IPv4 network; and

transmitting the replicated information from the second home agent server to the second stream server.

19. A method comprising:
