Receiver allocation in photonic bus networks

Photonic bus networks (PBNets) consist of a linear multihop structure interconnected in a dual unidirectional bus virtual topology using point-to-point optical channels. An analytic model is adapted for predicting the individual station delay of a PBNet where additional receivers have been assigned using the algorithms given by Todd et al. (1991). It has been found that the model works exceedingly well under all the cases considered. The success of the model is attributed to the fact that receiver allocation tends to reduce correlations in the flow of packets along the bus. As a result, the independence assumptions used in the model are more realistic.<>
