Present State and Future Developments

Kiev, 2003-04-04


Agenda

• Short brief of POL-34 history

• Structure

• Financial part (who pays for it, how)

• PIONIER programme– network infrastructure part – new model

Kiev, 2003-04-04


POL-34 – Historical background

• till 1993 – only NASK as academic provider• 1993 - MANs created

– NASK as backbone provider• using incumbent services

– NASK runs WARMAN (WARsaw MAN) – MANs own their networks !!!!

• 1997 - POL-34 created– backbone based on competitive bandwidth provider

• 1999/2000 – PIONIER programme

Kiev, 2003-04-04


Present Topology

POL-622?

Kiev, 2003-04-04


Structure - MANs

• MANs are telecommunication operators

• own their network (within city/region)– where possible

• use word „client”– universities, academies, research institutions

are clients– clients sign contracts

• MANs charge for their services

Kiev, 2003-04-04


Structure – POL34

• Agreement of 22 MAN/Supercomputing centres– not a company

• Network management – designated MAN (by contract)– nodes owned and managed by MANs

Kiev, 2003-04-04


Backbone cost sharing

• in total network cost

• not per link

• charges based on subsidy (50%), bandwidth (50%)

• risk sharing

• common connection to GEANT

• common peering connections and policies

Kiev, 2003-04-04


More facts

• Unified equipment (at the backbone layer) / common calls for tenders

• No direct way of funding additional activities within the network

Kiev, 2003-04-04


Decision making

• Decisions– by agreement– not by voting !!!!

• Is it a good model ?– hard to meet– hard too decide– everything is public– representation is not clear– everyone has voice and vote

it works !!!!!!

Kiev, 2003-04-04


Who pays for it ?

• State Committee for Scientific Research

• 22 subsidies / 22 budgets – on yearly basis– total cost of present network: 10 mln EURO (est.)

• MANs allowed to provide commercial services – to subsidise basic activity– without compromising „mission” services– MAN level / using infrastructure overcapacity– do not do it unless necessary/ officially approved

Kiev, 2003-04-04


Who pays for it ? (2)

• Example: Regional Silesian REN– KBN subsidy– edu users payments– com users payments– about a third each

• Inter-MAN services:– 60% of income to end MANs– 40% to common budget

Kiev, 2003-04-04


PIONIER – planned topology

Kiev, 2003-04-04


PIONIER – why we are building it?

• community needs an advanced network– demands are increasing– EU cooperation

• providers cannot deliver– not at required technological level– not at reasonable prices

Kiev, 2003-04-04


PIONIER – new model

• Previously (backbone, POL-34):– capacity rented– nodes owned by MANs

• Soon: all owned by community– fibres (dark) – transmission equipment – nodes– cost shared with com partners

Kiev, 2003-04-04


PIONIER - ownership

• dark fibres – financed from KBN (SCfSR) subsidy– owned by designated MAN– available to MANs for regional connections

(at the cost of ownership)– cost shared with commercial partners– obtained for the real cost not the commercial

value

Kiev, 2003-04-04


PIONIER – ownership (2)

• transmission/regeneration equipment– owned by operator (designated MAN)– financed from KBN (SCfSR) subsidy

• nodes– owned by local MAN !!!!– financed from (SCfSR) subsidy
