Low radix switch

WebLow-level router (low-radix router) has been widely used in the traditional parallel interconnection networks. Its transmission medium is electric, with a number of multi-pin parallel ports, which may cause a lot of signal loss. WebWe 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. Conference
