Is there a model/formula that can be used to estimate the time it takes from
the time a packet is detected lost to the time the actual retransmission
should takes place?
What is the "time a packet is detected lost"?

Also is there a similar formula for FWD-TSN? to obtain the time it takes from
the expiration time to the time the FWD-TSN is transmitted??
The FWD-TSN is transmitted whenever the corresponding TSN would be transmitted.
The expiration time has nothing to do with the sending time of the
FWD-TSN except for it must be in the past...

Just want to have a common base to compare with so I can check if the traces I
am getting are correct or not.

Any references, papers would be appreciated.

regards,
Horacio
