proprietary routing protocols are very adaptive. just don't throw the bln

I don't understand what the obsession with per-packet load balancing
is and why people have such a hard time understanding how a 4 tuple
load share hash(<source,sport,dest,destport>) could be uneven. In
case you haven't noticed, you are selling a bursty service. Since you
asserted that netflow switching is the best crisco has to offer, it
is quite possible that you haven't noticed. As for dCEF, read the docs
at cisco.. they tend to explain things so you don't have to ask questions.
