One can't take the word "inifinite" literally and still try to give a
sensible answer.

What bandwidth would truly be "sufficiently large" that you would
never need to consider the need to give some traffic preference over
other?  That would be the case if every link and switching device in
the network had sufficient capacity to carry all the traffic that
could conceivably directed through it by the concerted action of all
the end nodes.

Do you still want to pursue the question under those terms?  I don't.
