Amazon Web Services Randomized Network Graph (RNG) Data Center Architecture

completed

Amazon Web Services (AWS) replaced the traditional fat-tree network architecture inside data centers with a new design called Randomized Network Graph (RNG). This architecture uses quasi-random graphs to create a flat network topology allowing data to take multiple paths between points, improving efficiency and reducing costs. It includes innovations like the Spraypoint routing protocol and ShuffleBoxes passive optical devices, leading to cost savings of 9% to 45% and energy use reduction by up to 46% during peak cooling periods.
