In recent years, international organizations that manage IP addresses, and relevant organizations in the Asia Pacific and European regions, have noted the exhaustion of the IPv4 address space and, as a result, have promoted the transition to IPv6. At the same time, the ability to continue using existing systems based on IPv4 is a crucial issue, especially for Internet server environments which require the use of IPv4 global addresses. Once IPv4 address space is exhausted, there will be no more IPv4 addresses available for allocation, which is expected to make it impossible to add new servers. Although datacenters and other systems will be designed to run on IPv6 networks in the future, it is still important to ensure an environment on those networks in which IPv4 addresses can continue to be used.
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.
