I think it is more likely to hit a dynamic equilibrium: the % of packets dropped increases proportionately as the queue gets fuller.
That will likely happen, yes.
Otherwise I suspect it will become bursty: queue goes over 50% and is increasing, we start dropping packets, the queue starts to shrink, we start accepting packets for a while, the queue starts to grow, we start dropping packets again...
Why is that a problem? It's also a dynamic equilibrium.
OTOH, we wouldn't get the full benefit of this unless the NASes implement exponential backoff. If they just resend packets every 3 seconds, say, then an overload situation will remain an overload situation anyway.
Exactly. RFC 5080 specifies a backoff method, but no one uses it. Alan DeKok.
