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., life casting) 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 connects to the first user'"'"'s content via an IPv4 web interface.

Claims

1. A system comprising:

a stream server, coupled to an Internet Protocol version 4 (IPv4) network;

a first home agent, coupled to the stream server via a first IPv4 network connection and coupled to a Internet Protocol version 6 (IPv6) network;

a plurality of recipient IPv4 client devices, coupled to the stream server via a plurality of second IPv4 network connections; and

a first source IPv6 client device, coupled through the IPv6 network to the first home agent, wherein the first source IPv6 client device sends information to the first home agent comprising an IPv4 address, an IPv6 address associated with the first source IPv6 client device, and when no client is connected to a stream of the first source IPv6 client device, a binding update message, and video streamed from the first source client device to the stream server passes through the IPv6 network and the first IPv4 network connection; and

a second home agent, coupled to the stream server via a second IPv4 network connection, wherein the first home agent replicates the information transferred from the first source IPv6 client device and transmits the replicated information to the second home agent,

the first source IPv6 client device is coupled via a IPv6-over-IPv4 tunnel to the first home agent,

through the IPv6-over-IPv4 tunnel, information is transferred from the first IPv6 client device to the first home agent server in an encrypted form, and

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

2. The system of claim 1 comprising:

a second source IPv6 client device, coupled through the IPv6 network to the first home agent, wherein video streamed from the second source client device to the stream server passes through the IPv6 network and the first IPv4 network connection,

wherein the second source IPv6 client device is coupled via a native IPv6 connection to the first home agent.

3. The system of claim 1 wherein the video is streamed in a first format from the first source client device over the IPv6 network to the first home agent, and the first home agent transcodes the video into a second format and streams the video in the second format to the stream server via the first IPv4 network connection.

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

5. The system of claim 1 wherein the system comprises a third home agent, coupled to the IPv6 network, and

the first home agent transmits video streamed to the first home agent to the third home agent via the IPv6 network.

6. The system of claim 5 comprising:

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

7. The system of claim 1 wherein video is streamed from the first source client device in an encrypted format over the IPv6 network.

8. The system of claim 1 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 source IPv6 client device without using a IPv6-over-IPv4 tunnel to the stream server.

9. The system of claim 8 wherein each of the recipient IPv4 client devices cannot view an IPv6 address of the first source IPv6 client device.

10. The system of claim 8 wherein the first home agent functions as a proxy for the first IPv6 client.

11. The system of claim 1 wherein the first home agent is coupled to a IPv6 network, and the system comprises:

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

12. The system of claim 1 wherein at the first source IPv6 client device, storing a home agent client executable code, wherein when executed the executable code causes display on a screen of the first source IPv6 client device a sign-on graphical interface comprising a password input.

13. The system of claim 1 wherein the information transferred from the first source IPv6 client device comprises a video stream.

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

a second stream server, coupled to the second home agent via the IPv4 network, wherein the replicated information is transmitted from the second home agent to the second stream server.

15. The system of claim 1 wherein at the first home agent, encrypted information received from the first IPv6 client is decrypted into an unencrypted format.

16. The system of claim 1 information streamed to the first home agent is transmitted to the second home agent via an IPv6 network.

17. The system of claim 1 comprising:

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

18. The system of claim 1 wherein the information comprises a video stream, and the video stream is streamed in a first format from the first source IPv6 client device to the first home agent, 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.
