The National Dark Fibre Facility (NDFF) will provide the UK National Research Facility for dark fibre network research. A dark fibre network is a communications network, where it is possible to access and control the network at the optical layer, Layer1 (physical layer) in the seven layer Open Systems Interconnection (OSI) model of communications networks which underpins the internet. NDFF will be a new, fully remotely configurable, flexible and high capacity research facility, building upon the success of the National Dark Fibre Infrastructure Service (NDFIS1) dark fibre network (2013-2018). This will allow UK universities and their industrial collaborators to develop and demonstrate future networks which require access to or control of the optical layer (OSI Layer1). NDFF will comprise: 1. A dark fibre network of scale sufficient for experiments representative of real-world applications (>600 km). Users will be able to connect their equipment directly to the installed fibres and control the optical layer, allowing experiments on new techniques, such as quantum encoded data, adaptive spectrum slicing and Software Defined Networks (SDN).2. User experiment areas at multiple access nodes to interface directly with NDFF dark fibre. Interconnection for traffic generation and experiment control will also be possible UK-wide at Layer2 through services such as Janet Netpath.3. Remotely programmable amplifiers, switches and dispersion compensation modules which will enable the transmission characteristics of the network to be varied and will allow dynamic configuration of the network topology by users. 4. Wavelength Selective Switches (WSS) to split optical channels into separate optical fibres (or merge them into one fibre). A Flexgrid WSS gives user defined channel widths, enabling research on new utilisation models for the optical spectrum, increasing available logical topologies and allowing concurrent experiments using different optical wavelengths. 5. A remotely configurable Layer2 and above network to enable research into dynamic and intelligent network management. 6. An SDN and Network Function Virtualisation (NFV) research platform for UK researchers, enabling them to upload network policies directly, monitoring and manipulating the optical properties of the network. UK researchers will be able to develop and test networks having optimised latency, traffic grooming, energy consumption or security properties.7. A distributed processing infrastructure by linking sites that host servers, storage, memory and sensing. This will provide opportunities to study distributed Cloud and Fog infrastructures connected by high capacity reconfigurable optical networks. It will also provide nerve nodes that can perform network analytics offering users a new level of network programmability and adaptation.8. The ability to test concepts in network security and resilience across all seven OSI model layers, something that is impossible with other networks. This is of particular importance as networks are starting to introduce software control and flexibility at Layer1, creating new security and resilience challenges for network control. 9. Training using dedicated research and technician support. Administration, user interface and dissemination will be the responsibility of a dedicated facility manager. In order to achieve the full potential of the facility, it is crucial to engage with the UK research community and promote the service. NDFF will engage in UK and international meetings and will bring together users at an annual user day. Web-based interfaces with users and potential users will be further developed.

国家暗纤维设施（NDFF）将为暗纤维网络研究提供英国国家研究设施。暗光纤网络是一种通信网络，其中可以在支撑互联网的通信网络的七层开放系统互连（OSI）模型中的光学层、第1层（物理层）处访问和控制网络。NDFF将是一个全新的、完全远程可配置的、灵活的高容量研究设施，建立在国家暗光纤基础设施服务（NDFIS 1）暗光纤网络（2013-2018）的成功基础上。这将使英国大学及其工业合作者能够开发和演示需要访问或控制光学层（OSI第1层）的未来网络。NDFF将包括：1.暗光纤网络的规模足以进行代表现实世界应用的实验（>600公里）。用户将能够将他们的设备直接连接到已安装的光纤并控制光学层，从而允许对新技术进行实验，例如量子编码数据，自适应频谱切片和软件定义网络（SDN）。在多个接入节点处的用户实验区直接与NDFF暗光纤接口。通过Janet Netpath等服务，在第2层也可以在英国范围内实现通信量生成和实验控制的互连。远程可编程放大器、开关和色散补偿模块，使网络的传输特性能够变化，并允许用户动态配置网络拓扑结构。4.波长选择开关（WSS）将光通道分成单独的光纤（或将它们合并到一根光纤中）。Flexgrid WSS为用户提供自定义的信道宽度，从而能够研究光谱的新利用模型，增加可用的逻辑拓扑，并允许使用不同的光波长进行并发实验。5.一种可远程配置的第2层及以上网络，用于研究动态和智能网络管理。6.为英国研究人员提供的SDN和网络功能虚拟化（NFV）研究平台，使他们能够直接上传网络策略，监控和操纵网络的光学特性。英国研究人员将能够开发和测试具有优化延迟、流量疏导、能耗或安全属性的网络。通过链接托管服务器、存储、内存和传感的站点来实现分布式处理基础设施。这将为研究通过高容量可重构光网络连接的分布式云和雾基础设施提供机会。它还将提供可以执行网络分析的神经节点，为用户提供新级别的网络可编程性和适应性。能够跨所有七个OSI模型层测试网络安全和弹性概念，这在其他网络中是不可能的。这一点尤其重要，因为网络开始在第1层引入软件控制和灵活性，为网络控制带来了新的安全性和弹性挑战。9.利用专门的研究和技术支持进行培训。行政、用户界面和传播将由一名专职设施管理员负责。为了充分发挥该设施的潜力，与英国研究界合作并推广该服务至关重要。NDFF将参加英国和国际会议，并将在年度用户日将用户聚集在一起。将进一步开发与用户和潜在用户的网络接口。
