Both of you are totally wrong, because the proper thing to do
here is to police, if *ANY*, based on total traffic without
detecting any flow.

100 50Mbps flows are as harmful as 1 5Gbps flow.

Moreover, as David Hubbard wrote:

there is no point of policing.

Detection of elephant flows were wrongly considered useful
with flow driven architecture to automatically bypass L3
processing for the flows, when L3 processing capability
were wrongly considered limited.

Then, topology driven architecture of MPLS appeared, even
though topology driven is flow driven (you can't put inner
labels of MPLS without knowing detailed routing information
at the destinations, which is hidden at the source through
route aggregation, on demand after detecting flows.)
