Dual-Plane Isomorphic Hypercube Network

Abstract

We propose a multi-plane isomorphic network that increases network throughput and reduces network latency by effectively configuring multi-plane networks. In the proposed network, each plane adopts the same graph topology but different switch-to-switch connections. We evaluate the dual-plane isomorphic hypercube network by graph analysis and cycle level simulation. Results of the graph analysis show that the dual-plane isomorphic 8-hypercube reduces the average shortest path length by 22% and improves throughput by 28% compared with the dual-plane hypercube. Similar improvements are confirmed from the results of the cycle level simulation. We also examine the dual-plane isomorphic folded-hypercube network. Finally, we discuss the effect of longer cable length caused by the isomorphic network on the network cost and latency.
