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 -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,
