SprintNet: A high performance server-centric network architecture for data centers

Abstract

This paper presents the design, implementation and evaluation of SprintNet, a novel network architecture for data centers. SprintNet achieves high performance in network capacity, fault tolerance, and network latency. SprintNet is also a scalable, yet low-diameter network architecture where the maximum shortest distance between any pair of servers can be limited by no more than four and is independent of the number of layers. The specially designed routing schemes for SprintNet strengthen its merits. Both theoretical analysis and simulation experiments are conducted to evaluate its overall performance with respect to average path length, aggregate bottleneck throughput, and fault tolerance.
