    I believe (based solely on a single long-ago observation that an M/M/1/K
    queuing model seemed to predict the measured behaviour of core routers
    with short buffers pretty accurately) that the speculation in your third
    sentence above may in fact be true.  To relate this to another recent
    thread on this list, however, this seems like one of those things that
    should require no speculation since it is not so difficult to measure, yet
    I know of no good-quality data from "typical" core circuits which has been
    published anywhere.  The network we've built is constructed with insufficient
    instrumentation to enable us to understand what it is we've built with any
   certainty, so we speculate.
