Study of Performance Standards, kick off (Task 1.1.1) Robert Stoy DFN

Explore the study of performance standards and measurement tools for network performance evaluation at a kickoff event in Cork. The session covers methodologies from IETF, ITU-T, and active/passive measurement tools for Layer 3 and Layer 4 protocols. Learn about available path bandwidth, TCP throughput, and more. Discover DFN-IPPM and RIPE-TTM examples and research activities in bandwidth estimation tools.

  2. Overview <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 2

  3. Standardization IETF, RFCs • Layer 3 • Framework for IP Performance Metrics RFC 2330 • A One-way Delay Metric for IPPM RFC 2679 • A One-way Packet Loss Metric for IPPM RFC 2680 • A Round-trip Delay Metric for IPPM RFC 2681 • One-way Loss Pattern Sample Metrics RFC 3357 • IP Packet Delay Variation Metric for IPPM RFC 3393 • Layer 4 • IPPM Metrics for Measuring Connectivity RFC 2678 • A Framework for Defining Empirical Bulk Transfer Capacity Metrics RFC 3148 • Network performance measurement for periodic streams RFC 3432 <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 3

  4. Standardization IETF, Internet Drafts • A One-way Active Measurement Protocol (OWAMP) • draft-ietf-ippm-owdp-07.txt • A One-way Active Measurement Protocol Requirements • draft-ietf-ippm-owdp-reqs-06.tx • IPPM metrics registry • draft-ietf-ippm-metrics-registry-05.txt • IPPM reporting MIB • draft-ietf-ippm-reporting-mib-05.txt • Packet Reordering Metric for IPPM • draft-ietf-ippm-reordering-05.txt <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 4

  5. 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 <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 5

  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 <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 6

  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 <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 7

  8. Other Working Groups • GGF • Internet2 WGs, e2epi <JRA4 Meeting, EGEE Conference, Cork>, <20.04.2004> - 8
