Abstract

In this paper we focus on optical time division multiplexed (TDM) switching and its main distinguishing characteristics compared with other optical subwavelength switching technologies.We review and discuss in detail the synchronization requirements that allow for proper switching operation. In addition, we propose a novel synchronization algorithm that enables automatic synchronization of software defined networking controlled all-optical TDM switching nodes connected in a ring network. Besides providing synchronization, the algorithmalso can facilitate dynamic slot size change and failure detection. We experimentally validate the algorithm behavior and achieve correct operation for three different ring lengths. Moreover,we experimentally demonstrate data plane connectivity in a ring network composed of three nodes and show successful wavelength division multiplexing space division multiplexing transmission and switching of data bursts when using the proposed algorithm to provide synchronization.

随机长度环网中snd控制光TDM交换的同步

本文重点研究了光时分复用(TDM)交换技术及其与其他光亚波长交换技术的主要区别特征。我们将详细回顾和讨论允许适当切换操作的同步需求。此外，我们提出了一种新的同步算法，可以实现环形网络中连接的软件定义网络控制全光TDM交换节点的自动同步。除了提供同步之外，该算法还可以实现插槽大小的动态变化和故障检测。我们通过实验验证了算法的行为，并在三种不同的环长度下实现了正确的操作。此外，我们还通过实验验证了由三个节点组成的环形网络中数据平面的连通性，并在使用该算法提供同步时成功地实现了波分复用、空分复用、数据突发的传输和交换。
