[J Pan <Pan@uvic.ca>]

latency is based on round-trip time, and one-way delay includes
transmission delay, propagation delay, queuing delay and processing
delay. bandwidth does affect transmission delay (or serialization
delay), propagation delay is determined by the link length and the
"travel" speed of the signal, queuing delay is the hardest part and
affected by the buffer bloat a lot, and processing delay is another
variable. of course, transmission delay takes less and less portion of
the end-to-end delay now due to higher and higher "speed" links

consumers may mistaken the speed of the link (the "width" of their
pipe) as how fast their internet is (the "length" of the pipe), due to
the poor terminology we have been using ;-)
