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

5. 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)

6. 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.

7. 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?

8. 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?

9. Communication between boxes and with other type of boxes (IETF)
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?

10. Who can commit for some effort?
Who is interested?
