If you only measure 1 endpoint there is no way to tell where the packets are lost.

That is why doing measurement on 1 point only is …. insufficient for real troubleshooting.

Unfiltered traffic on both nodes may show some extra ICMP traffic warning you of issues somewhere on your path.

(MTU path discovery for example)

HI Everyone,

I have a network like bellow. I captured pcap over node1 interface. I was checking pcap's statistics. My question is that when i get "tcp.analysis.lost_segment" , Does it mean these packets are lost through node0 to node1 (path1 +path2) or these lost packets happened over path2?

        path1                                path2
              .................Router...............
         .                                           .
       .                                               .
node 0                                                  node1

I sent this question in http://stackoverflow.com/questions/42060182/wireshark-analysis-for-packet-loss but i have not received any  reply there. I hope your guide.

Thanks in advance
