“…In another word, only arriving at the correct height is achieved through the routing. A previous study specifically on the angular effect of Data Vortex can be found in [17]. A traffic control mechanism is implemented to support such routing rules and eliminate traffic contention and needs for separate optical buffering.…”

“…The modular architecture enables several possible topologies for the same number of I/O ports. It has been shown that for a given number of ports, a shorter height and greater number of angles provide lower latencies as compared to taller (large ) and narrower (small ) topologies [10].…”

“…Detailed performance studies have been pursued in simulation to characterize the utility of various modifications to the architecture, control, network dimensions, and injection/ejection polices of a standard data vortex architecture [10]. In addition to system-scale considerations, the implementation of the next-generation data vortex system will benefit greatly from improvements at the device level.…”

Abstract-A complete review of the data vortex optical packet switched (OPS) interconnection network architecture is presented. The distributed multistage network topology is based on a banyan structure and incorporates a deflection routing scheme ideally suited for implementation with optical components. An implemented 12-port system prototype employs broadband semiconductor optical amplifier switching nodes and is capable of successfully routing multichannel wavelength-division multiplexing packets while maintaining practically error-free signal integrity (BER 10 12 ) with median latencies of 110 ns. Packet contentions are resolved without the use of optical buffers via a distributed deflection routing control scheme. The entire payload path in the optical domain exhibits a capacity of nearly 1 Tb/s. Further experimental measurements investigate the OPS interconnection network's flexibility and robustness in terms of optical power dynamic range and network timing. Subsequent experimental investigations support the physical layer scalability of the implemented architecture and serve to substantiate the merits of the data vortex OPS network architectural paradigm. Finally, modified design considerations that aim to increase the network throughput and device-level performance are presented.Index Terms-Interconnection networks (multiprocessor), optical interconnections, packet switching, photonic switching systems, wavelength-division multiplexing.

“…For the same number of I/O port, the cost of network P is between network Q and network Q'. The angular resolution in the last cylinder was not included in this study due to its dependence of exit buffer strategy, but we should keep that in mind when we examine the results of different angle networks [4]. Fig.6 shows the latency and throughput performance comparison of the three networks respectively.…”

Data Vortex networks with different routing and forwarding path arrangements are studied. To keep the bufferless routing nodes, the binary tree decoding stages in Data Vortex network are shown to achieve best combined routing performance in throughput and latency. When k is too large, the general k-ary decoding stages introduce too much deflection latency penalty, so this paper focuses on the performance comparison between the binary tree (k=2) decoding and 4-ary decoding (k=4) cases. The results have shown that even though a much smaller number of cylinder levels are required in a network of k=4, there is only slight reduction in the average packet latency within the network. On the other hand, the traffic backpressure induced throughput limit and the additional implementation cost in 4-ary decoding networks have proved that binary tree decoding stages offer the optimum performance under bufferless operations. The study has in part shown the advantages of Data Vortex network topology over many two dimensional multiple stage interconnection networks (MIN) if only deflection is allowed for bufferless operation.
