Standardization ITU-T
• SDH and optical Quality and availability targets for end-to-end international constant
bit-rate digital paths • G.820–G.829
Error performance parameters and objectives for multi-operator international paths within the Optical Transport Network (OTN)
• G.8201

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
<JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 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
