This paper presents a detailed examination of a novel data center network (DCN) that can satisfy the high capacity and low latency requirements of modern cloud computing applications. This reconfigurable architecture called AgileDCN uses fast-switching optical components with a centralized control function and workload scheduler. By providing a highly flexible optical network fabric between server racks, very high network efficiencies can be achieved even under imbalanced loading patterns. Our simulation results show that, at high (70%) loads, TCP flow completion times in the AgileDCN are significantly lower than in an equivalent electronic leaf-spine network.

AgileDCN：敏捷可重构光数据中心网络架构

本文详细介绍了一种新型数据中心网络 (DCN)，它可以满足现代云计算应用程序的高容量和低延迟要求。这种称为 AgileDCN 的可重构架构使用具有集中控制功能和工作负载调度程序的快速切换光学组件。通过在服务器机架之间提供高度灵活的光网络结构，即使在负载模式不平衡的情况下也可以实现非常高的网络效率。我们的模拟结果表明，在高 (70%) 负载下，AgileDCN 中的 TCP 流完成时间明显低于等效的电子叶脊网络。
