P-Torus: Torus-based Optical Packet Switching Architecture for intra-Data Centre Networks

We introduce an intra-Data Centre, WDM-based, optical packet switching architecture. P-Torus demonstrates low energy footprint, CapEx/OpEx and low end-to-end latency relying on the combination of passive switching schemes and Torus architectures that enable single-hop interconnects for 256 ToR switches.
