“…A prototype evaluation switching node (Fig. 14) has been implemented with the aforementioned Schmitt trigger comparator circuitry, the D-SOA devices mentioned in Section IV-G, and the control logic by means of complex programmable logic devices [22]. The addition of a hysteric response increases the noise margins of the electronic decision logic by maintaining exaggerated transition thresholds.…”

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.

“…Each of these devices includes a switching network that is executed according to a given switching structure. The studies that have been carried out, both those that focused on theoretical aspects [6][7][8][9][10], and those related to the execution of large optical nodes [11,12], indicate that one of the most effective switching structures that ensures high scalability is the multistage Clos network. A multi-stage Clos network, both optical and electronic, allows nodes with large capacities (with a large number of inputs and outputs) to be constructed using switching elements with small capacities.…”

This article proposes a new analytical method of determining occupancy distribution and blocking probability in multiservice switching networks with admission control mechanisms and resource management mechanisms. The proposed method is a universal one, which allows for determining blocking probability using the same model, regardless of the type of admission control mechanisms and resource management mechanisms. The versatility of the method is demonstrated in the article for two selected mechanisms, i.e. a threshold mechanism and a resource reservation mechanisms. The switching networks under consideration are offered multiservice traffic streams, generated by the so-called multiservice sources, according to Erlang, Engset and Pascal distributions. The proposed method is based on a generalised way of determining traffic characteristics for inter-stage links of switching networks with resource and call management mechanisms. Particular attention is given to determining the influence of the introduced mechanisms in outgoing links of the switching network on the traffic properties of inter-stage links of the network. The results of analytical calculations are then compared with the results obtained in digital simulation for a number of selected switching networks.

In this paper, we study the internal blocking problem in optical Multistage Interconnection Networks (MINs). We introduce algorithms to resolve internal blocking in optical MINs based on buffering and/or wavelength conversion. Since the computations involved in some of the introduced algorithms are so little, they can be implemented in real time effectively. A simulation program has been developed to verify the performance enhancement gained using the algorithms. Simulation results indicate that the developed algorithms effectively decreased the internal blocking and thus increased the network performance.
