To address these issues, Fujitsu developed SA46T-AS, a technology that makes it possible to share IPv4 addresses and communicate on an IPv6 network. In June 2012 at Interop Tokyo 2012, Fujitsu presented a basic proof of concept for the technology that was carried out as part of a small-scale test among servers. Key to demonstrating the practicality of SA46T-AS technology is the implementation of technology that automatically enables large-scale deployment of virtual servers that use SA46T-AS, with no need for manual operation or individual settings. Moreover, it is also essential to be able to show that performance of the technology in a large-scale environment is sufficient enough to be practical.
Home > Press Release > Fujitsu Sees Success in Large-Scale Test of Technology to Solve IPv4 Address Space Exhaustion Issue
Fujitsu Limited, Fujitsu Computer Technologies Limited, the National Institute of Information and Communications Technology (NICT), and the Japan Advanced Institute of Science and Technology (JAIST) today announced that they recently conducted a successful large-scale test of a solution technology that will enable IPv4 addresses to be assigned (shared) to different devices at datacenters configured with IPv6 networks.
The test succeeded at running SA46T-AS(*1) - a technology developed by Fujitsu for sharing IPv4 addresses on IPv6 networks, announced June 12, 2012 - using StarBED(*2), NICT’s large-scale network testbed. For the first time the test confirmed automatic large-scale operations, with no need for manual operation or individual settings, even with virtual servers running SA46T-AS on StarBED.
The success of the test on a large-scale network demonstrated the practicality of SA46T-AS. This, in turn, will make it possible for multiple devices that employ IPv4 addresses - which are still in widespread use despite the fact that IPv4 address space is becoming scarce - to share a single IPv4 address, rather than each needing to be assigned their own separate address. As a result, it will be possible to continue and even augment the use of IPv4.
Details of this technology will be presented at the 6th Internet and Operations Technology Symposium (IOTS2013), to be held from December 12-13 at Hiroshima University.

Fujitsu: Developed SA46T-AS technology, oversaw test implementation
Fujitsu Computer Technologies: Developed and tested large-scale deployment technologies
NICT: Provided StarBED environment and advised on large-scale virtualization technologies
JAIST: Provided general advice on large-scale testing for the project
The partners in this project are pleased to contribute to the broader Internet community with this “made-in-Japan” technology that supports both the full-scale transition to IPv6 and the continued use of IPv4. As such, the organizations are currently pursuing a standards proposal for the technology with the IETF(*3).
