Press Announcement

Fujitsu announced that it has developed the SA46T/SA46T-AS Datacenter Solutions, a technology enabling datacenters to migrate smoothly from IPv4 to IPv6.

This technology is based on SA46T, which makes it possible to carry 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 boosts 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 datacenter.

Another advantage is that a single IPv4 address can be shared among some 65,000 machines. Sharing 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. 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 are promoting a transition to IPv6 with the World IPv6 Launch. Datacenters that operate cloud and outsourcing services typically use VLAN technology, which logically divides the IPv4 addresses used by their customers' systems in order to accommodate them without interference.

This means that at most about 1,000 companies (assuming 4 VLANs per customer) can be accommodated. Furthermore, with depletion of the IPv4 address space, it will become impossible to expand services run on IPv4, making support for IPv6 a pressing matter.
