An optical switching architecture for hierarchical group communication
2003
Journal of systems architecture
We show that the problem of finding the maximum passable subset of a permutation through a banyan is NP-complete. We then describe a two-level optical interconnection structure for groups or clusters of end-nodes (LANs or processors). At the higher level, an optical banyan is used to switch wavelength multiplexed packets from the groups. Technologically difficult switching of individual wavelengths is avoided by prearranging transmissions from the groups in a way that they can be switched in a
