Feldmeier) Subject: Avalanche I suspect that on an Ethernet, this would be a bigger mess because of the multiple collisions. I wouldn't expect multiple collisions, just one: then the ``randomness'' in the backoff times ought to break the symmetry. This is an interesting way to get collisions though. Usually the biggest cause of Ethernet collisions is the transmission of a long packet. If two other hosts become ready to transmit during that time, they will both begin transmitting shortly after the long packet's end. Curious, the gateway's broadcast acts as a synchronizing event, so that the independent transmission times assumption fails. --Jim
