abstract = {This paper provides new loss models for a hybrid
optical switch (HOS) combining optical circuit switching (OCS) and optical burst
switching (OBS). Exact blocking probabilities are computed when 1) no priority
is given to either circuits or bursts and 2) circuits are given preemptive
priority over bursts. Because it is difficult to exactly compute in realistic
scenarios, computationally scalable approximations are derived for the blocking
probability. The sensitivity of the analytical results to burst length and
circuit holding-time distributions is quantified by simulation. It is
demonstrated how the proposed approximations can be used for multiplexing-gain
evaluation of a hybrid switch. In addition, the extension of the proposed
single-node model to a network model composed of OCS, OBS, and hybrid switches
is outlined.}
