  1. How CESNET Got Access to Dark Fibres Jan Gruntorád Managing Director CESNET Czech Republic SERENATE NREN Workshop February 4 – 5, 2003

  2. Presentation overwiev • CESNET introduction • Access to dark fibers • Conclusions

  3. Brief History of Internet in CZ 1990 – connection of the Czech Republic to EARN/BITNET 1991 – first experiments with TCP/IP protocol, grant “Establishment of the University IP Network” 1992 – Ministry of Education, Youth and Sports - 20 mil. of CZK, start operation of CESNET 1994 - INET Conference in Prague 1996 - leased line open to competition 2000 – 2,5 Gbps IP service between Prague - Brno 2001 – 2,5 Gbps country-wide infrastructure CESNET2 operational 2002 - 10 years of Internet services in Czech Republic

  4. CESNET, z. s. p. o.(1) • Established as legal entity – not for profit Association of Legal Entities (z.s.p.o.) (CESNET Network) • 27 Universities • Czech Academy of Science • Member of projects consortiums: • TEN-34 (TEN-34 CZ) • Quantum (TEN-155 CZ) • Géant (CESNET2) • Internet2 International Member

  5. CESNET, z. s. p. o. (2) • 47 staff members in Prague • more than 90 part-time member universities and academy of sciences staff • International activities: - TF - NGN - TERENA Working Groups - EU funded projects

  6. Funding • Research Intend: „High Speed National Research Network and Its New Applications“ • 1999-2003 • Supported by Ministry of Education, Youth and Sports of the Czech Republic: • Institutional Funds: 6.6 mil. EURO/ year • Members fees: 2.5 mil.EURO/ year

  7. Access to dark fiber 1996 - liberalization of the leased line provisioning - very positive role of the European Comission - strong lobbying required

  8. 1996 - call for tender for TEN-34 CZ (34 Mbps national infrastructure) Two offers 1) Czech Telecom - optical infrastructure available - price unrealistic - monopoly behavior 2) Czech Radiokomunikace - 34 Mbps microwave links - not proven technical solution - realistic price - co-operative approach

  9. 1996 – 1998 - several alternative providers (power, oil, gass distribution companies, railways, etc.) built fiber optic infrastructure - everyone start with infrastructure between major cities - everyone want to sell services (bandwidth) only

  10. 1999 Telecom market situation in CZ - offer much higher than demand Convinced one company (MERO) lease dark fiber between Praha – Brno for pilot project.

  11. Prague-Brno circuit capacity 2,5 Gbps

  12. 2000 January – 2,5 Gbps pilot IP service operational Partner (MERO) received: - payment (covering cost) - results of the pilot project (joined technical team) - extensive publicity in all types of media

  13. 2000 Summer - call for tender for 2,5 Gbps country-wide connectivity Fall - contracts for seven 2,5 Gbps lines with six suppliers signed (both dark fiber lease and „lambda“ services) - both CESNET and service providers provide and operate regenerators - fibre optics lenght is cca 50 – 80 % longer than road distance

  14. Last (First Mile Issue) - concept of „meeting“ point - joined investment of fiber provider, CESNET and local organization to fiber between „meeting“ point and CESNET PoP location

  15. Keopsys Optical Amplifiers connection

  16. Recomended aplications • Booster only - up to 180km • Booster with preamp - up to 220km • Booster with preamp and Raman - up to 270km

  18. Conclusions - competition is esential requirement (lobby for competition) - telecoms (bandwidth providers) must see NREN as partner – not a competitor (define and adhere to AUP) - PR activities on all levels are very importnant
