  • Arrangement for traversing an IPv4 network by IPv6 mobile nodes
    Publication number: 20050152298
    Abstract: A source IPv6 mobile node is configured for forwarding an IPv6 packet via an IPv4 connection with a destination IPv6 router. The IPv4 packet includes IPv4 source and destination addresses, a UDP source port and UDP destination port, and a synthetic tag address in the IPv6 destination address field. The synthetic tag address, a valid (routable) IPv6 care of address, has an address prefix routed to the IPv6 router. The address prefix specifies a forwarding protocol, the IPv4 destination address for the IPv6 router, and a site-level aggregation identifier. An address suffix for the synthetic tag address specifies the IPv4 source address, the UDP source port and UDP destination port. Hence, the synthetic tag address enables the destination IPv6 router to send an IPv6 reply packet back to the source IPv6 mobile node via the IPv4 network.
