Fujitsu has developed the SA46T/SA46T-AS Datacenter Solutions, a technology enabling datacentres to migrate from IPv4 to IPv6.
The technology is used for carrying IPv4 transmissions over an IPv6 network, as well as for SA46T-AS, which is capable of sharing a single IPv4 address across multiple servers.
This technology enhances the number of IPv4 networks that can be accommodated on an IPv6 network to approximately 4.3 billion, which in practical terms means there is no upper limit on accommodating customer systems at a datacentre.
With this new technology, a single IPv4 address can be shared among some 65,000 machines, and it can be conducted among either physical or virtual servers, which means existing IPv4-based servers can continue operating and new servers can be added in the future.
According to Fujitsu, servers can be incrementally adapted to IPv6 even after depletion of the IPv4 address space.
The institutions that control IP addresses internationally and in the Asia-Pacific region have depleted the IPv4 address space, and this depletion, it will become impossible to expand services run on IPv4, thus supporting the adoption IPv6 technology.
