Latency-optimized high performance Data Vortex optical switching network

This paper addresses the effect of latency optimization in large scale Data Vortex optical networks. A recently proposed strategy for path synchronization in Data Vortex networks allows for dramatic reduction of the physical delay. In particular, it can be shown that such optimization brings critical improvement to latency in large scale networks. In addition, several network enhancement techniques with additional resource have been proposed to reduce the routing hops and allows for overall better throughput. This paper explores the combination of both south-path-delay-optimization and enhancement techniques and provides a thorough examination of network performance in physical latency and throughput. As a result, a highly loaded network up to 10,000 I/O ports can maintain very small physical latency (<15 packet slots) under such optimization and enhancement. The throughput performance can be independently controlled by its redundant condition, but nearly 100% injection rate can be supported as long as the network redundancy is sufficient. The compromise between cost and performance should be taken into account. The results show that these recent development makes large scale Data Vortex networks much more feasible and can be easily adapted to support high performance computing and communication applications.
