abstract = {A hybrid switching system which provides
integrated packet and circuit switching is considered. The framing structure is
based on position multiplexing of the isochronous slots. The switch capacity is
dynamically allocated to meet the demand of the synchronous circuits. Due to
some wastage inherent in the framing structure, not all of the remaining
capacity is available for the packet switched traffic. In order to evaluate the
packet capacity, we derive the statistics of the effective bandwidth utilized by
the isochronous traffic. Three circuit allocation policies are considered:
repacking, first-fit and first-fit involving circuit blocking policy. The
analysis takes into consideration the waste created by these policies. Numerical
results are presented to compare between the efficiency of these schemes, and to
demonstrate, in each case, the effect of circuit loading on the effective
capacity utilized by the isochronous traffic which in turn determines the packet
capacity.}
