Abstract

Cloud computing and web applications have further highlighted the need for powerful data centers with large bandwidth and low power consumption. In order to provide such a large bandwidth, today's electronic data centers require high power levels. Furthermore, communications and devices are not always used to their full potential. Optical networks can be a proper option for data centers, as they can offer large and variable bandwidth with lower power consumption compared to their electronic counterparts. In this regard, a dynamic all-optical network architecture is proposed in this paper, with bandwidth reconfiguration capability and low latency to reduce energy consumption. This proposed architecture, called Flat Ball, offers dynamic bandwidth utilizing passive optical devices with low power consumption and latency. Under realistic data center traffic scenarios, the latency of this network is up to 50% lower than its electrical counterpart, while providing a much higher throughput and consuming up to 60% less power.

平球:数据中心光互连网络能量管理的动态拓扑结构

云计算和网络应用进一步突出了对具有大带宽和低功耗的强大数据中心的需求。为了提供如此大的带宽，当今的电子数据中心需要高功率水平。此外，通信和设备并不总是能够充分发挥其潜力。对于数据中心来说，光网络是一个合适的选择，因为与电子网络相比，它们可以提供大而可变的带宽，功耗更低。为此，本文提出了一种动态全光网络架构，该架构具有带宽重构能力和低延迟，以降低能耗。这种被称为Flat Ball的架构利用低功耗和低延迟的无源光学设备提供动态带宽。在现实的数据中心流量场景下，该网络的延迟比电气网络低50%，同时提供更高的吞吐量，功耗低60%。
