The European national research and education networks (NRENs) through the Greek NREN, the pan-European network GEANT2, and the Irish NREN, have established the first dynamic user-requested high-speed circuit between Ireland and Greece. The concept, known as “bandwidth-on-demand”, allows users to request network capacity according to their needs. This circuit will allow research and education network interconnectivity and distance learning possibilities offering a data transmission speed of up to 1 000 times faster than a commercial ADSL line for the transmission of high-resolution video.

The bandwidth is a dynamic manner to share information and establish clear distance learning communication. Ireland and Greece were the first countries to test this project but the circuit is expected to connect research workstations through GEANT2, the pan-European multi-gigabit with over 30 million users in 34 countries across the continent. GEANT2 offers a high-bandwidth network to Europe's research and education community.
