[e2e] Queue size of routers

i think routers in the core don't have a delay*bandwidth of buffer memory 
(though i could be wrong).  i think they limp by with 5-20 ms of buffering.  
if this is true, it may be the reason it works is that the "high level of 
aggregation" at the core really does mean that the load is fairly constant, 
without the peaks associated with looking at a single TCP's queue length.  
again, note all the caveats, etc., above.

cheers, Greg Minshall
