FOSphere: A Scalable and Modular Low Radix Fast Optical Switch Based Data Center Network

Abstract

We propose a novel scalable and modular low-radix fast optical switch based DCN with sphere topology (FOSphere). Numerical analyses on 10880-server indicates that FOSphere achieves 4.1 μs server-to-server latency and 2.6E-3 packet loss at load 0.4.
