perfSONAR 3.4 supports hosts with 2 network interfaces in such a way that you can run bandwidth tests on one interface and latency tests on the other, without conflict. Cool.

A buddy attended the recent Technology Exchange conference, where he heard that 3.4 will schedule tests in sequence, so that you don't have to worry about conflicts even if your host has just one interface.

The online docs for 3.4.1 still recommend using separate interfaces or hosts. So I think 3.4 doesn't solve the conflicting bandwidth/latency issue.

Correct?

Right now, the web GUI configuration only supports doing the separate interfaces, not co-scheduling. However, you can manually configure the tests to support co-scheduling the two, though, that’s been less well tested, and would be a bit less accurate. If you’d like to try that out, I can put together some documentation.

Cheers,
