Agenda
• Short brief of POL-34 history
• Structure
• Financial part (who pays for it, how)
• PIONIER programme– network infrastructure part – new model

POL-34 – Historical background
• till 1993 - NASK as academic provider• 1993 - MANs created
– NASK as backbone provider• using incumbent services
– MANs own their networks !!!!
• 1997 - POL-34 created– backbone based on competitive bandwidth provider
• 1999/2000 – PIONIER programme

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
Zagreb, 2002-09-22
NATO ANW: The Third CEENet Workshop on Network Management,
Structure
• Agreement of 22 MAN/Supercomputing centres– not a single company
• Network management – designated MAN (by contract)– nodes owned and managed by MANs
Zagreb, 2002-09-22
NATO ANW: The Third CEENet Workshop on Network Management,
Structure (2)
• Backbone cost sharing– in total network cost– not per link– charges based 50% on subsidy, 50% on bandwidth
• Unified equipment (at the backbone layer) / common calls for tenders
• No direct way of funding additional activities within the network
Zagreb, 2002-09-22
NATO ANW: The Third CEENet Workshop on Network Management,
Structure (3)
• Decisions– by agreement– not by voting !!!!
• Is it a good model ?– hard to meet– hard too decide– everything is public– representation is not clear
• It works !!!!
Zagreb, 2002-09-22
NATO ANW: The Third CEENet Workshop on Network Management,
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 services– MAN level – do not do it unless necessary
Zagreb, 2002-09-22
NATO ANW: The Third CEENet Workshop on Network Management,
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

PIONIER programme (2)
• Advanced network applications• Advanced network services
• Advanced network infrastructure• Advanced specialized infrastructure• International network connections
• Cooperation with:– commercial world– administration

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
Zagreb, 2002-09-22
NATO ANW: The Third CEENet Workshop on Network Management,
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
