ملخص: Spacial wavelength reuse, or destination stripping, increases the capacity of packet-switched unidirectional and bidirectional ring networks, and promotes them to support multicast tra.c. In this paper, an analytical model is developed to evaluate the maximum achievable transmitter throughput (i.e., the capacity) of such networks, in the presence of multicast tra.c. Furthermore, the mean access delay of a multicast packet is investigated by means of an approximate approach. The approach is based on the discrete Geom/Geom/1 queue and on the computation of blocking probabilities. The analysis is validated by simulations and the impact of self-similar tra.c is shown. This work o.ers an important and simple analytical tool to compare the impact of multicast on access delays and multicast capacity in future slotted ring networks.
