20 URAN: Financial principles
Sources of founding Traffic tarifications Tariffs M. Dombrougov, V.Galagan URAN-2003

21 URAN: sources of founding
Users 28 k$ Users 67 k$ Users 18 k$ Users 49 k$ Users 80 k$ NATO NIG 100 k$ NATO NIG 184 k$ NATO NIG 150 k$ NATO NIG 107 k$ ? State 57 k$ State 38 k$ State 47 k$ ? Cisco 250 k$ 1999 2000 2001 2002 2003 M. Dombrougov, V.Galagan URAN-2003

22 CEI: traffic tarification
Effective traffic: V = Vin-D Vout-D Vin-N Vout-N Typical correlation for user’s traffic: in : out = 5:1 day : night = 4:1 In this assumption the effective traffic is equal to the total bidirectional one M. Dombrougov, V.Galagan URAN-2003

23 Synchronous lines 64-1024 kbps M. Dombrougov, V.Galagan URAN-2003
CEI: maximal tarifs 2002 Asynchronous lines kbps Synchronous lines kbps Monthly traffic, GB Montly fee, $ (ex.TVA) 1 86 1,5 141 2 128 3 203 4 210 5 285 6 293 10 492 12 540 20 904 M. Dombrougov, V.Galagan URAN-2003

24 CEI: special tariffs for RC

25 Perspectives of connection to GÉANT
Technical possibilities New services Financing Questions ?? M. Dombrougov, V.Galagan URAN-2003

26 M. Dombrougov, V.Galagan URAN-2003
GÉANT multi-gigabit pan-European research network. 6.000 AS (from ) connected science and education institutes in Europe M. Dombrougov, V.Galagan URAN-2003

27 Technical possibilities
Nov established Ukrtelecom channel to GEANT (to Vienna over ACOnet) There are ATM/FR Ukrtelecom network with STM1(4) connection to RC-cities from Kiev. Implementation of new URAN accounting system based on new Cisco IOS features which permits to estimate separately user’s traffic to different channels and apply special low prices for GEANT traffic M. Dombrougov, V.Galagan URAN-2003

28 New services and possibilities
Distance learning Video conferencing Distance medical research and diagnostic Physical and biology researches Supercomputer resource sharing Others ? M. Dombrougov, V.Galagan URAN-2003

29 M. Dombrougov, V.Galagan URAN-2003
Financing State contribution in Ukrainian science and education area is financial support of Ukrtelecom for channel to Vienna Part of NATO grant NIG # for URAN is redirected for connection to GEANT channel International support of Ukraine NREN’s in directions: ATM/FR backbone connection equipment; optical lines; microwave city lines M. Dombrougov, V.Galagan URAN-2003

30 M. Dombrougov, V.Galagan URAN-2003
Questions (1) To Ukrtelecom: What is Ukrtelecom positions according to URAN collaboration and support? Is It possible to delivering the GEANT traffic to URAN for low price (10% from Internet)? Is it possible to implement ATM 155 Mbps connection URAN RC in 6-th cities? To ACOnet, GEANT: How long we may hope for the free of charge Ukraine connection to GEANT due to ACOnet (GEANT) grant? M. Dombrougov, V.Galagan URAN-2003

31 M. Dombrougov, V.Galagan URAN-2003
Questions (2) To Ukraine state authority: May we hope for Ukraine state contribution to GEANT (up to EURO per year) for long term connection ? To members of URAN user association: Will profit be from GEANT connection for science and education processes in Ukraine and Europe? M. Dombrougov, V.Galagan URAN-2003
