The title of the Hungarian publication:
A Jövő Internet Nemzeti Kutatási Program eredményei 2014
A Jövő Internet Kutatáskoordináció Központ jelentése, FIRCC jelentés 2014
The publication was supported by the FIRST - Future Internet Research, Services and Technology
TÁMOP-4.2.2.C-11/1/KONV-2012-0001 project, managed by the Subproject 8 of the FIRST project, called
FIRCC- Future Internet Research Coordination Centre.
The project has been supported by the European Union, co-financed by the European Social Fund.

The Internet may be the most significant engineering construction in the last decades,
its impacts spread on almost all areas of the society, economy, science and culture.
Therefore the research of the future of the Internet has outstanding importance. The
research of the Future Internet is intensive in Hungary and the Hungarian researchers
reached recognized results in the national and international research programmes.
Especially I highlight the cooperation and collaboration realized among the universities,
