  Abstract:
In optoelectronic OTIS architectures, electrical and optical interconnects are used for local and global communication, respectively. Interesting instances of the OTIS architecture are the OTIS-hypercube and OTIS-mesh. This paper conducts a performance evaluation and comparison of these networks under different structural conditions and traffic loads. All judgments made, are based on observations from extensive simulation results of the interconnection networks. We conclude that, when the OTIS-hypercube and equivalent 2-D OTIS-mesh are compared under the constraint of equal bisection bandwidth, the performance of the OTIS-hypercube is of superior performance. We however show that the conclusion drawn by Dally from the constraint based comparison of the hypercube and mesh networks can be extended to their OTIS counterparts when the constraint for comparison is equal intra-group bisection bandwidth.
