6. , - 6 Measurement Systems IPPM Measurement Systems  Online Active Measurements  Measurements of OWD, OWL, OWD, OWDJ  Data Archive  Presentation through web interface  Examples: DFN-IPPM, RIPE-TTM Layer4 and Application Measurement Systems  Not standardized

7. , - 7 Measurement Tools On IP layer lots of tools are exising, evolution to IPPM Measurement Systems and Metric Standardisation in IETF On Transport Layer (Layer 4)  interesting metric for data intensive GRIDs: ‚Available Path Bandwidth‘ TCP Throughput  measurement methods: state of the art: active measurements with real data streams, example ‚iperf‘. –heavy network load Passive Measurements: –Monitoring of router interfaces and data combination Bandwidth estimation tools: –research actvity, pilot apps available
