Topology Design for Large-Scale Interconnection Networks: A Modern Approach

Transforming Network Topology Design from Art to Science For decades, the design of large-scale network topologies has relied heavily on heuristic intuition and bottom-up engineering experience.While classic structures like Fat-tree have achieved immense success, the underlying mathematical principles governing their performance have remained largely implicit.This book introduces the first general framework capable of systematically generating and optimizing large-scale network topologies through a rigorous top-down approach.It reveals the hidden mathematical principles behind successful engineering designs, using Ramanujan graphs and combinatorial designs to achieve the optimal trade-off among various performance metrics. From clarifying the success of classic Fat-tree topology to designing future-proof AI clusters, this framework provides a universal blueprint for next-generation interconnection networks. It is an essential guide for researchers, engineers, industry professionals and
