“…Deflection routing can be used in these networks, but the performance of deflection routing with no buffering in networks not designed specifically for this method of routing is greatly reduced [34]. Both the omega and butterfly networks are simple and were designed for electrical store-and-forward routing.…”

Abstract-All optical path interconnection networks employing dense wavelength division multiplexing can provide vast improvements in supercomputer performance. However, the lack of efficient optical buffering requires investigation of new topologies and routing techniques. This paper introduces and evaluates the Data Vortex optical switching architecture which uses cylindrical routing paths as a packet buffering alternative. In addition, the impact of the number of angles on the overall network performance is studied through simulation. Using optimal topology configurations, the Data Vortex is compared to two existing switching architectures-butterfly and omega networks. The three networks are compared in terms of throughput, accepted traffic ratio, and average packet latency. The Data Vortex is shown to exhibit comparable latency and a higher acceptance rate (2x at 50 percent load) than the butterfly and omega topologies.Index Terms-Optical switch fabrics, optical switching, photonic packet switch, data vortex switch architecture, packet switching.

“…They have been used in parallel machines such as the HEP multiprocessor [48], the Connection machine [27], and the Caltech Mosaic C [47], as well as in high speed communication networks [34]. Hot-potato routing is appropriate for optical networks [1,25,34,52,55].…”

“…Below, we adapt the discussion from [15, Section 2] so that it is appropriate for trees. Consider a packet that was deflected at time t 1 by packet 1 . Define a deflection sequence and a deflection path with respect to this deflection as follows.…”

“…According to [1], let the network capacity C be defined as r·S·N c = --=-·-- (13) where r denotes the number of transceivers per node, S stands for the transmitting rate of each transmitter, N represents the number of nodes in the network, and h denotes the mean hop distance of the network. …”
