Hi, I am new to lwip. Just took over from someone who has left my organization. Could you tell me exactly which timer functions in lwIP? If I know it I can cross-check if they are getting called at regular intervals or not.
As I said my lwIP application does not have any OS. I have used a timer to call "tcp_fasttmr" and "tcp_slowtmr" at regular intervals. Are you referring to these functions? And if so, what is the interval at which "tcp_fasttmr" should be called and what interval "tcp_slowtmr" should be called? regards Anirudha ________________________________ From: Kieran Mansley <[email protected]> To: Mailing list for lwIP users <[email protected]> Sent: Thursday, 7 July 2011 14:07:11 Subject: Re: [lwip-users] (no subject) On Wed, 2011-07-06 at 18:40 +0800, Anirudha Sarangi wrote: > > If I run wireshark on the PC where jperf runs, the capture indicates > an "TCP out > of order" message.

If you weren't calling lwIP's timer functions at the correct intervals, one side effect would be that TCP retransmissions would be broken, which seems to match what you're describing.
