基于服务器中心无源光网络的数据中心架构实验评估
Experimental Evaluation of Server Centric Passive Optical Network Based Data Centre Architecture
摘要:
无源光网络(PON)技术最近被提出作为数据中心中的可扩展性、能量效率、高容量、低成本、灵活性和超额订阅问题的解决方案。本文实验演示和讨论了一个以服务器为中心的PON为基础的数据中心架构,具有高速和可靠性的实现。该架构是使用一组服务器建立的,这些服务器被分组到直接连接在一起的机架中,并通过网关服务器连接到光线路终端(OLT)。交换和路由功能已嵌入到使用4x10GE Xilinx NetFPGA的服务器中。通过使用IP摄像机通过WDM节点和PON网络传输长达110公里的光学连接的实时视频流,已经观察到了流量连续性。
英文摘要:
Passive optical networks (PON) technology has recently been proposed as a solution for scalability, energy efficiency, high capacity, low cost, flexibility and oversubscription issues in data centres. This paper experimentally demonstrates and discusses the implementation of a server centric PON based data centre architecture with high speed and reliability. The architecture is set up using a set of servers grouped into racks directly connected together and to the Optical Line Terminal (OLT) through gateway servers. The switching and routing functionalities have been embedded into servers using 4x10GE Xilinx NetFPGA. Flow continuity has been observed through live video streaming using IP cameras transmitting over up to 110 km optical connections through WDM nodes and the PON network.
