you can measure the number of bytes transmitted and received via SNMP if
you have an snmp hub and the proper software (assuming that the MIB will
allow you to get the info on a per port basis which is something that an
snmp hub should do).  if you have a cisco router you can turn on IP
accounting.  i did that to track the bandwith usage for 6 different
machines and i modified a perl script that sucks the info out so that a
web page is generated with the current total number of bytes transmitted
and received for the month, the page is generated hourly and the owners of
the systems can check to see how much bandwidth they have used up for the
month.  a freebsd box should work also but i did my setup a while ago
before i found out about ipfw.  it seems to me like the best method is via
snmp from a hub but the router or the freebsd box also work if you don't
have an snmp hub...
