Summary: TCP congestion with no dropping packets

Description bright_yuen126 2016-06-01 00:08:16 EDT
I'm trying to build a topology with a bottleneck like this:
        |     10Mbps
      /   \   100Mbps
     /     \
   node3  node4
then I run iperf -s on node 1 and iperf -c on node 3 and 4.

What confuse me is that although the speed of tcp transmission is lower down on both nodes, no packet loss(drop) is recorded in the .tr file.

I'm running dce-quagga and the ip-table is static.

Can anyone give some explaination?

Sorry for my carelessness, the problem has been solved.
I edited the source code of iperf which induced some error limiting the speed.

Thanks to all.
