[lwip-users] Maximum retransmission value

[PELISSIER Christophe]

Hi,

 

I want to speed up the connection error detection of my application.
Is decreasing the TCP_MAXRTX and TCP_SYNMAXRTX value a good way to be aware rapidely that a connection has been lost.

 

Is there any risk to decrease TCP_MAXRTX from 12 (default value in my lwipopts.h) to 6 and TCP_SYNMAXRTX from 6 to 3?

 

What can be the side effect that i must take care of?

 

Thanks for your support.

 

Regards,

Christophe
