The Opening Ceremony of “Future Network Test Facility: FITI (Future Internet Technology Infrastructure)” High-Performance Backbone Network was held at Tsinghua University on April 20. Representatives from the Ministry of Education, Tsinghua University and other project contractors witnessed the opening of FITI.

 

FITI is an important component of Future Network Test Facility, China’s first key national science and technology infrastructure project in the field of information. It is co-built by 40 colleges and universities such as Tsinghua University. Cored by native IPv6 technology, FITI covers 31 provinces, autonomous regions and municipalities across China, aimed at providing an international leading open experimental environment for China to study and design the architecture of future Internet. 

FTTI Topography

The core nodes of FITI backbone network are distributed in 40 colleges and universities in 35 cities of 31 provinces, autonomous regions and municipalities. It can provide all kinds of users with testing services at the physical layer, data link layer, network layer, transport layer and application layer of future Internet, and support FITI to shape a super large-scale future Internet testing environment with simulations of not less than 4,096 heterogeneous networks.

At present, the opened FITI high-performance backbone network connects the core nodes of 40 universities in 35 cities across China. The maximum bandwidth between the core nodes reaches 200 G, realizing interconnection with IPv4/IPv6 test facilities at home and abroad.

 

In early April, the number of IPv6 addresses of China surpassed the number of U.S. addresses and became the global first, to which FITI contributed a lot. FITI, on the basis of an independent /32 large-scale IPv6 address field, obtained the /20 super large-scale IPv6 address block allocated by APNIC, supporting FITI to become the world's largest future Internet test facility at present.

Noticeably, FITI is not simply based on a native IPv6 network. It can also support Source Address Validation Architecture (SAVA) of next-generation Internet.

SAVA supports the precise positioning and traceability of Internet end system addresses. It breaks through the key technology of security and credibility of the next-generation Internet architecture, and realizes large-scale application in the networks of national important departments and key industries. Major social and economic benefits have been achieved. So to speak, FITI is a huge network devoted to the exploration and practice of the core and key Internet technologies.

 

 

FITI is another major Internet experimental platform co-built by 40 colleges and universities, such as Tsinghua University, and the third huge network after CERNET and CERNET2.

CERNET, completed in 1994, marks the official opening of the first national computer internetwork independently designed and built by China with the TCP/IP protocol, which plays an extremely important role in promoting the development of Internet and its applications in China.

CERNET2, the core network of CNGI-- China's next-generation Internet demonstration project-- was completed in 2004, marking the beginning of Chinese exploration and research on the key technologies of Internet. CERNET2 innovatively adopted a native IPv6 technical architecture, and became an important fundamental test facility for China to study next-generation Internet technology, develop major applications, and promote the industrial development of next-generation Internet.

Compared with CERNET and CERNET2, FITI is focused on future Internet research and exploration for all kinds of scientific research units in China. FITI, committed to promoting the development of a community of shared future for mankind in cyberspace, is key national experimental infrastructure for future Internet, and will become an important strategic scientific and technological support for the implementation of "Cyberpower" by the country.
