• Establishment of gigabit NIL CESNET2 circuits, 189 and 169 km long• Acquisition of the first optical mile in other CESNET2 nodes• Preparation of long-distance single-fibre circuits4.1 International Collaboration andGlobal Lambda NetworkThe solution witnessed a significant change, as we succeeded in contracting thelambda service for 6 months, 2.5 Gbps from the CESNET2 Prague site to Nether-Light in Amsterdam (particularly thanks to successful tender procedures anda drop of prices for an international connectivity), and in ordering an opticaltransport system, Cisco 15454, used already in NetherLight, CERN, StarLight andCanet4. After a period of six months, the service may be extended or upgradedto 10 Gbps. We named the node of the lambda network in Prague CzechLightand its deployment is currently in progress. As a result we are becoming one ofthe few countries in the world with access to international lambda services forthe research.CAnet4LondonStockholmChicago/CAnet4Cisco 15454MEMSBorder routerStarLight10 GE1 GEBorder router2.5 GChicago/AmsterodamCisco 15454Alcatel 16702.5 G10 G Oct 2002Juniper T6402.5 GNY AbileneAmsterodamCisco 15454GroningenCisco 65092.5 G10 G Jan 2003PragueCisco 15454(US clusters)Alcatel 1670CERNCisco 15454Figure 4.1: Global lambda networkIn the first stage, CzechLight will be available by means of four GE connectionsand it will be used particularly for research in network services, for data transmissionsbetween CERN or Fermi-Lab and the Centre for Particle Physics inPrague, and for the connection of supercomputer networks in Europe and the40 High-speed National Research Network and its New Applications 2002
