TCP rto min,max

Christiaan Simons

Hi,

Need a hint on lwIP TCP.

Does anyone know the minimum
and maximum value for the RTO in lwIP?

Are these limits constants or
do I need to calculate these?

I think these values come from an RFC.  While the RTO may vary depending
on how much you have retransmitted recently, and may incorporate an
element of the RTT, there are upper and lower limits (which I think are
constants).

Hope that helps,

Kieran
