Customer Empowered Optical Networks - CESNET´s Approach Jan Gruntorád, Stanislav Šíma CESNET, z.s.p.o. Czech Republic Internet2 Member Meeting Arlington, April 9th, 2003

Presentation overwiev 1)CESNET introduction 2)Concept of Customer Empowered networks 3)Access to dark fibers 4)NIL – Nothing in Line concept 5)Future plans

CESNET, z. s. p. o.  Established as legal entity – not for profit Association of Legal Entities (z.s.p.o.) in 1996 Association of Legal Entities (z.s.p.o.) in 1996  27 Universities  Czech Academy of Science  48 staff members in Prague  more than 100 part-time member universities and academy of sciences staff and academy of sciences staff

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

Concept of Customer Empowered Networks - more flexibility for the „Customer“ - more cost effective - access to dark fibres essential

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

Prague-Brno circuit capacity 2,5 Gbps

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
