Thank you, Fabrice! > the backoff window is selected randomly between 0 and 2^BE-1.
According to you, the term of "the backoff window" seems to be used as the retransmission backoff or the retransmission backoff wait. If so, I was confused by a sentence in the third paragraph of the section, "A successful transmission in a shared link resets the backoff window to the minimum value." What is "reset" or the minimum value...? Perhaps, the backoff window there is meant (2^BE - 1) and its minimum value is (2^macMinBe - 1). > dedicated links > no collision / no backoff. > You transmit it without delay > (NB: you may have the first transmission during a shared link, and its > retransmission in a dedicated one) Yes, that how it works. > If I understand correctly the standard, in that case, the dedicated link > should not impact the BE value: the next packet will be picked in the queue, > and transmitted with the same BE value as previously. Hmm, what if that next packet is not acknowledged in the first attempt? Will it use the *same* BE value in the following retransmission as perviously or use macMinBe as described in the standard, which could be different from the BE value used previously...? > "NB is the number of times the CSMA-CA algorithm was required to back off > while attempting the current transmission" Aha, I see; then we need "NB=0" just after the "Retransmission?" box ;-) > I have also the same doubts as you for the figure 6.6…. It'd be great if someone is woking on revising the figure...
