so you have one ingress port ("the NAS"), 20 egress ports ("the clients").

Egress port 1 fills up.

What are you going to do?  Flow-control (-> slow down 19 other ports)
or drop?

(For "3 ingress ports, 1 egress ports, bursty traffic that doesn't
exceed the egress port speed *on average*", the answer is different)
