Ethereal can not calculate this.
However IF you have a flow of data where many full sized segments are sent towards that link back to back
you can estimate both the maximum link bandwidth as well as the average percentage utilization of that link by studying the
interframe gap between ACKs coming back.
It is very timeconsuming and boring job but it is possible.
maybe when we have fixed all the bugs someone could add expert code to ty to estimate for every tcp session the bandwidth of the slowest link on the path and the percent utilization it has.

I know that from the summary screen you can get
average packets/s & average packet size. So there must be some way of
calculating the utilisation as a percentage of the 100M port?
Any ideas?
