Thanks for the response. For some reason my sessions are denied, which I think I mistook earlier for most sites not providing UDP test endpoints at all. For example:

bwctl -c llnl-pt1.es.net -u -b200m -T iperf3
...
bwctl: SessionRequest: Denied by llnl-pt1.es.net

are you coming from a uw.edu address? That should work.

Maybe try without the -b option and see what happens.

 

Even if the session was allowed, 200Mbps isn't much of a test for what I'm testing. I was hoping for 1-5Gbps, but that might be asking too much.

Yeah, thats too risky, as Dale pointed out. There might be a tight link in the path that that would torpedo.

    You can run UDP tests at speeds up to 200Mbps to the ESnet test hosts.

    List of hosts are here:

    Sample command:

    bwctl -c llnl-pt1.es.net <http://llnl-pt1.es.net> -u -b200m -T iperf3

        I'm attempting to locate perfSONAR/bwctl endpoints in the US
        that are open for public UDP tests. It seems like most sites
        allow TCP tests but deny UDP tests. Why is this? Could someone
        recommend some UDP endpoints I might be able to connect to?

        Thanks,
