For internet link bandwidth reporting, I'd take a look at ntop. You may need
to enable a mirror port on your switch to "see" this traffic to and from the
internet.

For an internal network bandwidth, I'd suggest using an SNMP capable switch
and a problem like cacti or MRTG graphing bandwidth on each switch port.
NTOP can help with internal bandwidth reporting, but the mirror port setup
is more complicated in a single switch internal network.

Hope this helps,
