About FB Feel6

FB Feel6 connection Service, based on FreeBit proprietary technology "Feel6", is designed for large scale testbed environmnet to achieve the concept of "enabling anyone to feel IPv6 without having to deal with technical difficulties".

The core concept of FB Feel6 is not just an issue of IPv6 connection, but is about presenting to people what IPv6 world is all about. With this perspective, our effort is to focus on how to provide participants with the most user friendly environment in not having to deal with troublesome computing environment settings, but providing end-users with an easily adoptable test bed via present Internet environment.
For FB Feel6, many unique services are prepared, from receiving the latest news to checking email of Home PC from anywhere "outside" and listening to specific radio broadcast.....etc
Let's try IPv6 world now!


Abbreviation of Internet Protocol Version 6. The glue that holds the Internet together is the network layer protocol IP (Internet Protocl). There are various IP versions; present version is Version 4(IPv4) . The specification of IPv4 was revealed backed in 1984 and even today it is still being widely used. However, because of rapid expansion of Internet users and the evolvement of Internet usage, IPv4 has long been predicted and criticized as limited. In order to solve the above issue and to adjust/adopt for Internet growth, IPv6 is now positioned to replace IPv4. The main characteristic of IPv6 is the availability of the overwhelmingly large number of IP addresses. Because of this, home products, such as refrigerator or even vehicle can all be assigned with an IP address. With this capability, many technologies are expected to emerge for the purpose of security enforcement and mobile deployment from various industries.



Feel6 is a technology of FB-DTCP v4v6 tunneling, which based on DTCP(Dynamic Tunneling Control Protocol)from IETF Draft. Feel6 technology enables IPv6 communications between DTCP Client and Tunnel Server on existing networks (IPv4). DTCP Controller is a 64bit implementation for large scale sessions management.


Today, the expectations for IPv6 is expanding, but due to uncertainties for the IPv6 market, key players, such as communication hardware makers, telecommunication carriers and ISPs, are facing difficulties and often reluctant to make large scale investments and to take bold steps for IPv6, hence a "negative spiral" effect result. In order to break through this "negative spiral", from March, 2003 to the end of September, FreeBit, a network and technology solution provider to ISP, and WIDE Project, Japan's most remarkable Internet booster, cooperated and performed an extensive IPv6 test bed based on proprietary FreeBit's technology. With this test bed, we succeeded in proving to the rest of the world that Japanese ISP's were "IPv6 Ready". It is "FB Feel6 Connection Service” which was started as an IPv6 connection service.
