1. 1 QoS monitoring and SLS auditing TF-NGN, Athens October 16 th, 2001 Victor Reijs

2. 2 QoS monitoring and SLS auditing Aim of session Status update… Determine the future work…

3. 3 QoS monitoring and SLS auditing Outline Deliverable D9.4 is final One-way delay without GPS is possible –Who wants to test Measurement Protocol… Measurement infrastructure...

4. 4 QoS monitoring and SLS auditing Measurement Protocol IETF IPPM Originally for One-way delay, now: –1 and 2 way, active measurements –Control part –Measurement part –Data transfer part

5. 5 QoS monitoring and SLS auditing Measurement infrastructure

6. 6 QoS monitoring and SLS auditing Specification of infrastructure (1) Flexible platform –different tests –different accuracy/granularity –new ideas –downloading code Support active and passive measurements

7. 7 QoS monitoring and SLS auditing Specification of infrastructure (2) Secure –access to tests –trustable results –firewalls Exchangeable measurements Measurements over multiple domains Manageable infrastructure

8. 8 QoS monitoring and SLS auditing Specification of infrastructure (3) Independent on OS –IOS, Linux, Windows,... Resource management –CPU load, link load,... Based on standards –Measurement Protocol

9. 9 QoS monitoring and SLS auditing Help needed!!! Who wants to help to build such an infrastructure? victor.reijs@heanet.ie
