[lwip-users] LWIP and sliding window

[Yann Suisini]

ello ,


Currently I'm using the KEIL TCPnet stack on my system (ARM LPC23xx) .
It's working well on a LAN with low latency (about 650KB/s on the embedded
ftp server with SD card access).
But I can only send frames one at one , waiting for an ACK before I can send
another frame .
So with high ping about 300ms on a intercontinental connection , I  get this
:

1500 bytes sent
300ms before ack
1500 bytes sent
300ms for ACK...

So the max I get in this case is about 3.5 KB/s  !!!

I would replace this stack by Lwip but I would know if I cand send more than
one frames before waiting for an ACK
in order to optimize use of the bandwith. So , does Lwip manges tcp
windowing ?


thanks in advance !

Yann.
