Abstract:
1. A method comprising: providing a home agent server, operating in an Internet Protocol version 4 (IPv4) network, managing Internet Protocol version 6 (IPv6) clients; providing a first IPv6 client and second IPv6 client coupled to the home agent via the IPv4 network; from the first IPv6 client, sending to the home agent an IPv4 address and IPv6 address associated with the first IPv6 client; from the second IPv6 client, sending to the home agent an IPv4 address and IPv6 address associated with the second IPv6 client; when the first and second IPv6 clients are connected to the home agent, implementing a first IPv6-over-IPv4 tunnel in the IPv4 network between the first IPv6 client and the second IPv6 client, wherein the first IPv6-over-IPv4 tunnel does not pass through the home agent; and from the first IPv6 client, transferring data in an encrypted form using the first IPv6-over-IPv4 tunnel directly from the first IPv6 client to the second IPv6 client, where the data does not pass through the home agent.
