Abstract:
One example embodiment provides a method and system where a node in an IPv6 utility network communicates with an IPv6 destination node through and IPv4 network. IPv6 utility nodes are reachable through at least one access point. IPv6 packets to be transmitted between an IPv6 access point and an IPv6 destination node through a IPv4 communications network are encapsulated in IPv4 packets for transmission through the IPv4 communications network. Packets received after transmission through the IPv4 communications network at the destination node are extracted to retrieve the IPv6 packet.
