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<sup>-12</sup>) 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.
