Claim:
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.
