Abstract

Alternative contention resolution techniques are studied in the data vortex interconnection network, namely, the insertion of fiber-delay-line (FDL) buffers into the switching nodes. The performance of each technique is evaluated according to relevant performance metrics: acceptance rate, mean latency, and latency variance. A detailed discussion concludes that while traditional data vortex networks perform better in terms of throughput, FDL-based switching nodes have a favorable impact in reducing the system latency.
