Abstract
This paper analyzes queueing behavior subject to
multiplexing a stochastic process M(n) of flows, and not a
constant as conventionally assumed. By first considering the case
when M(n) is iid, it is shown that flows’ multiplexing ‘hurts’
the queue size (i.e., the queue size increases in distribution). The
simplicity of the iid case enables the quantification of the ‘best’
and ‘worst’ distributions of M(n), i.e., minimizing/maximizing
the queue size. The more general, and also realistic, case when
M(n) is Markov-modulated reveals an interesting behavior:
flows’ multiplexing ‘hurts’ but only when the multiplexed flows
are sufficiently long. An important caveat raised by such observations
is that the conventional approximation of M(n) by a
constant can be very misleading for queueing analysis.
