  1. Access to dark fiber in Serbia & Montenegro NREN – National Research and Education Network of Serbia & Montenegro Zoran Jovanović Slavko Gajin Belgrade University Computing Center

  6. Where are we now • Completing the national Gbps backbone • Completing the Gbps MAN networks in Belgrade, Nis and Novi Sad. • Starting the Gbps backbone in Kragujevac • Expanding the network to high schools and even primary schools • Establishing services • For the first time normal international connectivity - SEEREN

  7. Newest technology • Avoiding the PST infrastructure and using dark fiber • Low end newest technology (still 1 Gbps) • 500 times higher capacity on the internal backbone and 45 times higher capacity for international connectivity in 3 years • Dark fiber to individual institutions – wherever possible • Investments are very low compared to POS solutions

  8. Cooperation! • Exceptional cooperation of all universities, Ministry of Science and Technology and Telekom Srbija • Even without a legal entity, all key players were pushing in the same direction • Contracts with Telekom Srbija where we guaranteed that the NREN cannot be used for any form of commercial traffic (according to GEANT AUP) • Young team of experts at university computing centers throughout the country

  9. Conclusions (1) • From 0.1%of the backbone capacities of developed countries, we reached about 40%. • Capacity of the international connectivity is below 1%of the capacity of most developed countries. • All Web and FTP traffic on international links is still passing through proxy servers • We believe that our technological solution has the best price/perfomance • There will be a fast increase in the number of users of the network • Our wish is to soon be on the better side of the digital divide – at least for the NREN

  10. Conclusions (2) • The development was done under the following circumstances: destroyed economy, 600.000 refugees, more than 1.000.000. unemployed and very low salaries. Donations like SEEREN were crucial. • Our NREN had the best possible support, especially from the Ministry of Science, Technology and Development of Serbia • Cooperation with Telekom Srbija, when clear AUP is defined in contracts, opened the access to dark fiber • New services on the NREN are emerging – distant learning, GRID infrastructure, … • Our Network Information System NetIS is already expanding to the SEEREN network

  11. SEEREN • The best way to change the less developed SEE countries • Exceptional cooperation between participants – new friendships • Coordination by GrNet in SEEREN and EU and NATO proposals at the highest level • Thanks to EU, GrNet, DFN, Hungarnet, RoEduNet, Dante, Cesnet and CEENET for helping us to make a great step forward • Best investment in the future of the region
