The National Dark Fibre Facility (NDFF) provides 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 provides a fully remotely configurable, flexible and high capacity research facility, building upon the success of the National Dark Fibre Infrastructure Service (NDFIS) dark fibre network (2013-2018). This allows 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 comprises: 1. A dark fibre network of scale sufficient for experiments representative of real-world applications (>1,000 km). Users are 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). The equipment included in this proposal supports quantum secured networking, sensing and experiments with novel spectrum usage.2. User experiment areas at multiple Access Points to interface directly with NDFF dark fibre. This proposal includes provision for extension of the dark-fibre network to assist in meeting user needs. Interconnection for traffic generation and experiment control is also possible UK-wide at Layer2 through services such as Janet Netpath+.3. Remotely programmable amplifiers, switches and dispersion compensation modules which enable the transmission characteristics of the network to be varied and allow dynamic configuration of the network topology by users. L-Band operation over part of the network is also supported.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 which will interface with 6G Wireless research under this proposal. 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 are 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 of CDT Students and other researchers using dedicated research and technician support. Administration, user interface and dissemination are the responsibility of a dedicated facility manager. The proposed equipment enhancement, which is the result of extensive consultation with Users and benefits from the advice of experts from the NDFF External Advisory Board, will provide improved access, operational and measurement facilities.

国家黑暗纤维设施（NDFF）为英国国家研究机构提供了黑暗纤维网络研究。深色光纤网络是一个通信网络，可以在其中访问和控制七层开放系统互连（OSI）通信网络中的layer1（物理层）的网络，该模型是基于Internet的通信网络。 NDFF提供了一个完全可配置，灵活和高容量研究设施的基础，这是基于国家深色纤维基础设施服务（NDFIS）Dark Fiber网络（2013-2018）的成功。这使英国大学及其工业合作者可以开发和演示未来的网络，这些网络需要访问或控制光学层（OSI Layer1）。 NDFF包括：1。一个深色的尺度网络，足以代表现实世界应用的实验（> 1,000 km）。用户能够将其设备直接连接到已安装的纤维并控制光学层，从而实验新技术，例如量子编码数据，自适应频谱切片和软件定义的网络（SDN）。该提案中包含的设备支持新型频谱使用情况的量子安全网络，传感和实验2。用户实验区域在多个接入点直接与NDFF深色纤维接口。该建议包括扩展深色纤维网络的规定，以帮助满足用户需求。通过珍妮特·纳特（Janet Netpath）等服务，在第2层的英国也可能在英国范围内进行交通生成和实验控制的互连。远程可编程的放大器，开关和色散补偿模块，使网络的传输特性变化，并允许用户对网络拓扑的动态配置。还支持了网络部分上的L波段操作4。波长选择性开关（WSS）将光通道拆分为单独的光纤（或将其合并为一个光纤）。 FlexGrid WSS为用户定义的通道宽度提供了对光谱的新利用模型的研究，从而增加了可用的逻辑拓扑，并允许使用不同的光波长进行并发实验。5。可远程配置的第2层及以上网络，可实现对动态和智能网络管理的研究，该网络将与该建议下的6G无线研究接口。 6。英国研究人员的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，监视和操纵网络的光学特性。英国研究人员能够开发和测试具有优化延迟，流量修饰，能源消耗或安全性的网络。7。通过链接托管服务器，存储，内存和传感的站点来进行分布式处理基础架构。这将为研究由高容量可重构光网络连接的分布式云和雾基础架构提供机会。它还将提供可以执行网络分析的神经节点，从而为用户提供新的网络可编程性和适应性。8。在所有七个OSI模型层中测试网络安全性和弹性的概念的能力，其他网络是不可能的。这尤其重要，因为网络开始在第1层引入软件控制和灵活性，从而为网络控制带来了新的安全性和弹性挑战。 9。使用专门的研究和技术人员支持对CDT学生和其他研究人员的培训。管理，用户界面和传播是专用设施经理的责任。拟议的设备增强功能是与用户进行广泛咨询的结果，并在NDFF外部顾问委员会的专家建议中受益，将提供改进的访问，运营和测量设施。
