Planar Layout of Data Vortex Optical Network

This paper aims to explore an alternative planar layout of the Data Vortex optical network. It is desirable to provide high throughput and low latency information exchange between processors or Input/ Output (I/O) ports within advanced multiprocessor computing and communication systems. Optical interconnection networks can overcome many limits in electrical interconnection networks and provide promising routing performance. This paper extends previous research in (Yang, 2012) that proposed an alternative planar layout of the Data Vortex optical network. The original cylindrical structure can be converted to a configuration that consists of multiple parallel planes. Since the new layout is designed to be functionally equivalent to the original network, its routing performance in throughput and latency is shown to be very similar to that of the original network under the same network conditions. A more thorough performance comparison is provided by exploring various traffic conditions, load conditions and network sizes. The effect of the traffic injection angles is investigated for optimized performance. Finally the overall network layouts in physical system implementation have been explored based on the planar cylindrical levels. The proposed designs are simple and flexible to satisfy the synchronization requirement and scalability needs. The modular design is versatile in adapting to different network sizes and it provides an attractive solution for future system integration.
