RE: [lwip-users] lwIP TCP connection stalls?

[Grubb, Jared]

Does it stall for a few seconds and then resume? I was seeing this on my system, and the stall was occurring on the host computer. The reason was that the TCP window on my lwIP board was small enough that Window’s Nagle algorithm was kicking in. Might not apply to your system, but is just a thought.

Hi,

 

I am having a problem where the TCP connection between a linux client and lwIP’s TCP stalls randomly i.e. the traffic flow between the two endpoints stops completely. I came across the following thread in the mailing list with similar symptoms;

 

http://lists.gnu.org/archive/html/lwip-users/2006-10/msg00114.html

 

However I didn’t see a resolution for it. Does anybody know the resolution?

 

PS: My application is a transparent TCP proxy using only the TCP layer from lwIP. I am analyzing the pcap dumps using tcptrace/xplot. If people would like to take a look at the traces for themselves let me know and I will post the pcaps. I am sure people like tracing tcp flows J

 

Regards

Ram
