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.

from the home agent server, transmitting the information in the unencrypted format to a first stream server of a plurality of stream servers over an IPv4 connection;

from the first stream server, transmitting the information in the unencrypted format to a plurality of IPv4 client devices using an IPv4 connection;

from the home agent server, transmitting the unencrypted second stream to a first stream server of a plurality of stream servers; and

from the first stream server, transmitting the unencrypted second stream in the unencrypted format to a plurality of IPv4 client devices using IPv4 connections.

2. The method of claim 1 comprising:

executing client software code at the first IPv6-over-IPv4 client to generate the first message;

from the home agent, transmitting an address in the IPv4 network for the first IPv6-over-IPv4 client to use; and

executing client software code at the first IPv6-over-IPv4 client to generate a second message to the address in the IPv4 address.

3. The method of claim 2 wherein the first message and the second message are encrypted.

4. The method of claim 1 comprising:

providing a usage database; and

storing usage information received from the first stream server in the usage database.

5. The method of claim 1 comprising:

providing a first stream of a first stream format to be transmitted by the first IPv6-over-IPv4 client;

executing client software code at the first IPv6-over-IPv4 client; and

using the client software code, transcoding the first stream into a second stream of a second stream format, different from the first stream format, wherein the information transferred from the first IPv6-over-IPv4 client to the home agent is the second stream.

6. The method of claim 5 wherein the first stream comprises video data and the second stream comprises video data.

7. The method of claim 1 wherein the client software code performs the step of from the first IPv6-over-IPv4 client, sending to the home agent server a first message comprising an IPv4 address and IPv6 address associated with the first IPv6-over-IPv4 client.

8. The method of claim 1 wherein the home agent server performs routing of IPv6 data on layer 3 of the OSI model.

9. The method of claim 1 comprising:

at the home agent server, deencapsulating IPv6-over-IPv4 tunnel so that the IPv6 video stream viewable by the IPv4 Internet to viewing users through a Web site.

10. The method of claim 1 comprising:

providing an IPv6 database of IPv6-over-IPv4 clients;

transmitting the IPv6 database to a plurality of home agent servers; and

using the IPv6 database, directing an IPv4 client to one of the home agent servers.

11. A method comprising:

providing a home agent server, coupled to an Internet Protocol version 4 (IPv4) network, managing Internet Protocol version 6 (IPv6) clients;

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

executing client software code at the first IPv6-over-IPv4 client;

from the first IPv6-over-IPv4 client, using the client software code, sending to the home agent server a first message comprising an IPv4 address and IPv6 address associated with the first IPv6-over-IPv4 client;

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

providing as a first stream of a first stream format for transfer by the first IPv6-over-IPv4 client;

using the client software code, converting the first stream to a second of a second stream format, different form the first stream format;

through the first IPv6-over-IPv4 tunnel, transferring the second stream from the first IPv6-over-IPv4 client directly to home agent server in an encrypted format over the IPv4 network;

at the home agent server, decrypting the encrypted second stream from the first IPv6 client into unencrypted format;

from the home agent server, transmitting the unencrypted second stream to a first stream server of a plurality of stream servers; and

from the first stream server, transmitting the unencrypted second stream in the unencrypted format to a plurality of IPv4 client devices using IPv4 connections.

12. The method of claim 11 comprising:

providing an IPv6 database of IPv6-over-IPv4 clients;

transmitting the IPv6 database to a plurality of home agent servers; and

using the IPv6 database, directing an IPv4 client to one of the home agent servers.

13. The method of claim 12 comprising:

providing a usage database; and

storing usage information received from the first stream server in the usage database.

14. The method of claim 11 comprising:

receiving a request from an additional IPv4 client to receive the first stream from the first IPv6-over-IPv4 client;

from the second stream server, transmitting the replicated second stream to the additional IPv4 client.

15. A method comprising:

providing a home agent server, coupled to an Internet Protocol version 4 (IPv4) network, managing Internet Protocol version 6 (IPv6) clients;
