Abstract

This paper compares two optical switching architectures: the feed-forward and the recirculation, based on practical considerations, such as the size of the optical switching fabric. This work was stimulated by several papers in the technical literature claiming to address the above comparison. However, erroneously, these papers in their comparison rely on metrics borrowed from the `electronic' domain. Because the optical and the electronic domains differ so much, the conclusions presented in these papers are meaningless, at best. In this paper, we also discuss some additional properties of the feed-forward architectures, making them so much more attractive for wide-area all-optical connectivity.
