- Goals:
- Measure delay/jitter/loss between points
- Be able to fix any issues that come up
- Approach: Deployed measurement machines at the endpoints and a number of hosts in between and set up regular latency tests between the machines
- Benefits: Shows end-to-end problems, and allows a "Divide-and-Conquer" approach to narrow down the source of the problem
- Tools: OWAMP (Latency Tester) and perfSONAR-BUOY (Test Scheduling Framework)
- Analysis software was written or modified to make it easy to view and understand the data.
- Results: Several potential performance issues, in both the network and the monitoring systems, were identified, and all were solved and verified through diagnostics and monitoring
