I used this to identify some intermittent loss in one direction from I think Kyrgyzstan to the UK, There was a claim that sometime flows were fine and sometimes they weren't. Problem was an ECMP in Pakistan or Iran which was using udp port numbers to balance the flow. Could consistently get 25% loss with certain numbers and not with others.
