There is a fundamental question which must be asked before any answer to
this question can be considered - what type of LAN are you trying to get
bandwidth utilization numbers for? An Ethernet type LAN is extremely variable
based on the number of 'stations' or 'nodes', differences in nodal load and
collision detection timing, traffic rate per node etc. A token ring on the
other hand can be very predictable in it's performance.
