[Olsr-users] TCP flow in a 5-hops wifi network - experiment

Dear all,

I've correctly deployed my multi-hop wifi network, and I put OLSR into
running.
I am evaluating TCP transmission flows by means of IRPEF+JPERF (such useful
tool!).

My question is: have any of you ever experienced the following behaviour?
The TCP throughput falls to zero because OLSR TC messages collide, thus
provoking IP entries losses.
Hence, the path is corrupted, and the TCP transmission stops for few
seconds, until new TC messages are correctly received by all the nodes..

Thank you all in advance!

BR,
Marco
