Abstract:
An IPv4 node is able to send an IPv4 packet to an IPv4 destination via an IPv6 access network, based on translation of the IPv4 packet into an IPv6 packet for transmission via the IPv6 access network. The IPv4 packe is translated into the IPv6 packet by a local gateway. The IPv6 packet has an IPv6 source address that includes a prescribed address prefix assigned to the local gateway, and an IPv4 address of the IPv4 node. The IPv6 packet also includes an IPv6 destination address that includes a second a address prefix assigned to a remote gateway, and a second IPv4 adress of the IPv4 destination. The IPv6 packet is converted by the remote gateway into an IPv4 packet for reception by the IPv4 destination via an IPv4 network.
