OREANDA-NEWS. Fujitsu announced that it has developed SA46T Multiple Service Plane Expansion, which enables the continued use of IPv4 services, even with the deployment of IPv6. This is an important solution to the depletion of IPv4 addresses that is resulting from the increasing prevalence of PCs, servers and other Internet-connected communication devices.

SA46T Multiple Service Plane Expansion is comprised of three basic technologies. The first is SA46T, which is technology for backbone networks(1) that enables IPv4 communications to be transmitted over IPv6 networks. To this Fujitsu has added two newly developed technologies. One is SA46T-PR, which enables IPv4 communications over IPv6 on a stub network(2), and the other is SA46T-PT, which interconnects between the SA46T and SA46T-PR domains. SA46T Multiple Service Plane Expansion makes it possible to accommodate some 4.3 billion IPv4 services on an IPv6 network and improves scalability in terms of network size, regardless of physical distance across multiple countries.

Simply by implementing SA46T Multiple Service Plane Expansion on network equipment and making some simple settings, an IPv6 network can continue to support existing IPv4 services without interruption, enabling a smooth transition to IPv6.

A live demonstration of this technology will take place at Interop Tokyo 2013, running June 12-14 at Makuhari Messe, as part of Interop ShowNet, where verification tests of SA46T, SA46T-PR, and SA46T-PT will be conducted. This technology has been nominated for the Best of Show Award.
