Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, Piotr Sąsiedzki POL-34 Silesian University of Technology Computer Centre POL – 34 Organization and Financial Structure NATO Advanced Networking Workshop: The Third CEENet Workshop on Network Management

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, Agenda Short brief of POL-34 history Structure Financial part (who pays for it, how) PIONIER programme –network infrastructure part – new model

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, POL-34 – Historical background till NASK as academic provider MANs created –NASK as backbone provider using incumbent services –MANs own their networks !!!! POL-34 created –backbone based on competitive bandwidth provider 1999/2000 – PIONIER programme

POL-622?

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, 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, 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, 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, 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, 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, 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

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, IT infrastructure development programme for polish scientific community, years "PIONIER: Polish Optical Internet – Advanced Applications, Services and Technologies for the Information Society POLSKI INTERNET OPTYCZNY

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, PIONIER programme (2) Advanced network applications Advanced network services Advanced network infrastructure Advanced specialized infrastructure International network connections Cooperation with: –commercial world –administration

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, PIONIER – planned topology

Zagreb, NATO ANW: The Third CEENet Workshop on Network Management, 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, 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
