The major challenges in designing optical switched interconnection networks include the lack of optical buffering and the crosstalk originated from the optical switching elements. Vertical Stacking Banyan networks and Data Vortex networks provide two different approaches to solve the problem. Both networks utilize several parallel planes in conjunction with traffic scheduling to eliminate the contention and the crosstalk within the routing nodes. While the two share similar compromise between system cost and switch performance, their traffic control mechanism has fundamental difference due to specific configurations of the parallel routing planes. This paper provides a comparison study of two network approaches, focusing on the overall system complexity and the resulting switch performance in throughput and latency.
