在过去的十年里，全光网络（AON）技术的研究一直在进行，新的特性不断被开发出来。AON的优点包括大带宽供应、低延迟传输和低能耗。AON的基本概念是数据信号完全通过光域从源节点传输到目标节点，中间节点没有光-电-光（OEO）转换。用于实现AON的技术经历了一系列的发展，包括时分复用（TDM）、频分复用（FDM）和空分复用（SDM）。多维AON （MD-AON）引领未来AON架构的趋势，为云计算、物联网（IoT）等新兴应用提供了充满活力的状态。在本文中，我们回顾了基于不同全光交换和多路复用技术（即TDM， FDM和SDM）的AON架构的发展，这是本文关注的主要领域之一。另一个主要领域是详细讨论了实现AON的数据平面和控制平面技术以及资源优化技术。本文还介绍了几种AON测试平台及其组成和功能，以及基于这些测试平台可以实现的一些潜在应用场景
Research into all optical network (AON) technology has been ongoing over the past decade, and new features are constantly being developed. The advantages of AON include large-bandwidth provisioning, lowlatency transmission and low energy consumption. The basic concept underlying AON is transmission of data signals entirely through the optical domain from source to destination nodes, with no optical-electrical-optical (OEO) conversion at intermediate nodes. The technologies used to implement AON have undergone a series of evolutions, which encompass time division multiplexing (TDM), frequency division multiplexing (FDM), and space division multiplexing (SDM). Multi-dimensional AON (MD-AON), which leads the trend of AON’s future architecture, provides a vibrant state for emerging applications such as cloud computing and Internet of Things (IoT). In this article, we review the evolution of AON architectures based on the different all optical switching and multiplexing technologies (ie, TDM, FDM, and SDM), which is one of the main areas of focus in this article. The other main area is detailed discussion of implementations such as data plane and control plane technologies as well as resource optimization technologies for realizing AON. We also introduce several AON testbeds with their compositions and functions, and some potential application scenarios that can be implemented based on these testbeds
