Figure 3.9: Prague–Brno line, 2.5 Gbps in 20023.6.5 Development of Tools for Long-term InfrastructureMonitoringFor the purpose of long-term monitoring of the network infrastructure, we usethe GTDMS-II system, which is subject to further development. In 2002, we focusedon the extension of the spectrum of measured devices and on an analysisof the possibilities for system development from its current architecture,according to the objectives specified in an interim report concerning solutionsin 2001.The most significant extensions of the system include support for the measurementof the standby power supply units, with a particular focus on productsused in the backbone network, or precision of the measurements of profiledchannels. Also the methods concerning the initiation analysis of measured devicesreported considerable changes towards an decrease in the measurementaggressiveness.The analysis of the possibilities for further system development showed thenecessity to begin the year 2003 with a proposal for the next generation. Thisis particularly due to the vast implementation variability and dynamics of the32 High-speed National Research Network and its New Applications 2002
