Presentation Transcript

  1. Measurement Infrastructure

  2. Monitoring infrastructure • Multidomain monitoring infrastructure • OWD, IPDV, OWPL and traceroute per CoS - else? • SLA verification and service “health” • per link, edge-to-edge, end-to-end • Target: Q3 2003 • We are interested in • working in partnership with NRENs • feedback from community

  3. Monitoring infrastructure • Dedicated boxes for measuring • sessions established between the boxes according to what need to be monitored

  4. Phases • The work is divided in two phases: • the first one focuses on monitoring OWD, IPDV and OWPL. • the second one aims to monitor additional metrics (networks ones and user-visible metrics)

  5. Steps of the first phase • Define which metric have to be monitored and how to monitor them. • Which hardware, which OS and other technical issue + how to evaluate the measurement accuracy(?) • Build a monitoring box or modify an existing one. • Software to collect data, store and present them.

  6. Metrics challenges • OWD • meaningful measurements (from STM-1 to STM-64, ...), amount of traffic to be send (one probe or more?), pattern • measurement accuracy (< 1ms or several ms?) • go for GPS, but not available everywhere • How to test the measurement accuracy? • HW, OS impact on measurement? • How to present the results?

  7. Metrics challenges (cont) • IPDV • how far is it from what the applications ask for? • OWPL • how many packet have to be send per circuit speed? Which pattern to use?

  8. Data storage • RR database? • every packets or min, avg, max? • fileds needed in the packets? • Communication between boxes and with other type of boxes (IETF) • How to represent end-to-end as a succession of edge-to-edges?

  9. Who can commit for some effort? • Who is interested?
