Optical hierarchical fully shuffled tree

Abstract

This paper applies optical interconnects towards the implementation of fully shuffled r-ary trees. The architecture is based on wavelength division multiplexing (WDM)which enables multiple multi-access channels to be realized on a single optical fiber and dynamically varying the time slot and wavelength allocation according to traffic intensity, thus allowing for better performance. The system performance is evaluated in terms of the system delay factor of the single-hop and multi-hop virtual topology. Two physical communication pattems, geometric distribution and threshold mode, are applied to improve the system performance. KeywordsParallel processing, optical interconnection network, wavelength division multiple access (WDMA), optical hierarchical fully shuffled tree, static wavelength allocation, dynamic allocation, single-hop, and multi-hop.
