Pretty funny and good stuff....since no one really acheives true 100MB spee=
ds anyways=2C then
a 100MB port might actually traffic shape itself naturally!!! I forget what=
the actual speeds truly are...
is it 80% advertised speeds?
I'm not sure which is cheaper but I think Juniper has some low end Netscree=
ns you can try also
that have traffic shaping features.....
