无源光网络（PON）技术正日益成为现代数据中心的一个有吸引力的解决方案，因为它提供了节能、高容量、低成本、可扩展和灵活的连接。在本文中，我们报告了一个PON为基础的数据中心架构，提供高弹性和高速互连，通过在不同的机架服务器之间提供替代通信路由的实施。每个机架被分成若干组服务器，并通过一组充当中继服务器的服务器连接到其他机架和光线路终端（奥尔特）。我们使用4×10GE Xilinx NetFPGA在服务器内实现交换和路由功能，并演示了使用IP摄像机通过WDM节点和PON网络在长达100 km的光纤连接上实时视频流的端到端通信。
Passive optical networks (PON) technology is increasingly becoming an attractive solution in modern data centres as it provides energy efficient, high capacity, low cost, scalable and flexible connectivity. In this paper we report the implementation of a PON based data centre architecture that provides high resilience and high speed interconnections by providing alternative communication routes between servers in different racks. Each rack is divided into several groups of servers and connects to other racks and the Optical Line Terminal (OLT) through a set of server that acts as relay servers. We implement the switching and routing functionalities within servers using 4×10GE Xilinx NetFPGA, and demonstrate end-to-end communication using IP cameras live video streaming over up to 100 km optical connections through WDM nodes and the PON network.
