2002 - cesnet

For the purposes of preparing an original proposal for the ASTON project, wealso received an offer for international fibres which illustrates the possibilitiesfor an international lease of fibres.Within the scope of our international collaboration, being invited by the MaxPlanck Institute of Physics in Munich we took part in the preparation of theproject for regional research and education network in South-Eastern Europe.For the situation in this region, see Figure 4.3.A quote from the final recommendations expressed during the seminar:“Preference is expressed to establish sustainable cross-border connections onnew dark fibre with low running costs. The technical model of the Czech academicnetwork is considered as a guiding example in defining technical solutions.”Fibre Installation Lease LeaseLine length Price price period[km] [Euro] [km/pair/month] [years]Prague–Vohburg (D) 390 0 40 0Vohburg–Frankfurt a.

We succeeded in simplifying relationships between thedevelopment of network topology and routers, thanks to the proposal of a genericscheme of CESNET2 network, specifying the network characteristics thatare considered invariable. Based on this model, we made out a proposal of animplementation scheme, which was then discussed during researchers’ workshops.The collaboration with the network operators and administrators of themost important PoPs, although it was not easy, brought its rewards.42 High-speed National Research Network and its New Applications 2002
