In reality, the project reaches Latvia in 2001. Afterwards there are several follow-ups — GÉANT2, GÉANT3, GN3+, and until 2015 SigmaNet is actively involved in all of them. As of 2009, when GÉANT3 is launched, representatives of SigmaNet enthusiastically participate in the project related activities (NA2 T4 GÉANT PR Network Coordination, NA4 T3 User Identification and Liaison for Pan-European and Global Projects and Organisations, SA4 T2 Multi-Domain Security Services (MDSS)) by helping the project partners with their public relations and coordinating their activities, as well as by assessing different situations and suggesting solutions that enhance the security of academic networks in all countries involved in the project.

This project includes 11 countries from Northern Europe.

In 2006–2007, the IMCS UL takes part in the FP6 Porta Optica Study project that examines how to create optical fiber based research and education networks in the three Baltic states, as well as Ukraine, Belarus, Moldova, and Transcaucasian countries.
