monitoring infrastructure
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
monitoring infrastructure1
Monitoring infrastructure
  • Dedicated boxes for measuring
    • sessions established between the boxes according to what need to be monitored
phases
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)
steps of the first phase
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.
metrics challenges
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?
metrics challenges cont
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?
slide9
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?
