A new generation of metropolitan optical networks is needed to enable the vision of future 'Smart Cities', where urban population can access a new class of revolutionary ultra-reliable and low-latency network services such as autonomous driving, augmented reality and telemedicine. Metro networks will evolve from a rigid infrastructure, simply designed to collect end-user traffic, to a composite network-and-computing ecosystem that provides resources needed by an application. Given the importance of these network services to society, next-generation metro-area networks (NG-MAN) must be designed to be resilient against large disruptive events, such as natural disasters or terrorist attacks. This project will investigate novel resilience strategies for NG-MAN that incorporate new technical directions, technologies and edge computing. This research has the potential to enable a high level of availability of critical communications and services in disaster scenarios that affect metropolitan areas. This joint National Science Foundataion and Japan National Institute of Information and Communications Technology (NICT)-funded research project will provide new approaches to the design of disaster-resilient NG-MAN. There are three main research areas, to address complex network management and design problems arising in both the pre-disaster phase (i.e., prevention) and the post-disaster phase (i.e, recovery): i) Disaster-resilient control plane in NG-MAN. New strategies for control-plane protection will be studied, targeting a cognitive and hierarchical control-plane architecture that remains operational even if the main controllers fail. ii) Slice protection for a NG-MAN disaster-resilient data plane. Different disaster-resiliency approaches shall be enforced depending on the priority of different network slices and related services, considering all the elements composing a slice that must be protected, i.e., bandwidth, computing and storage resources. iii) Rapid recovery via deployable recovery units. Rapid post-disaster recovery of a network is critical, and is facilitated through use of movable devices, e.g., transported over specialized trucks to restore connectivity or computing facilities. (Mobile units were deployed after the 2011 earthquake and tsunami in Japan). This project will explore the deployment of optical burst mode amplifiers for recovery of fiber plant operation. Evaluation of the proposed approach will be performed using the NICT testbed in Sendai.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

需要新一代的城域光网络来实现未来“智慧城市”的愿景，其中城市人口可以访问新型革命性的超可靠和低延迟网络服务，例如自动驾驶、增强现实和远程医疗。城域网络将从简单地设计用于收集最终用户流量的刚性基础设施发展为提供应用程序所需资源的复合网络和计算生态系统。鉴于这些网络服务对社会的重要性，下一代城域网 (NG-MAN) 的设计必须能够抵御自然灾害或恐怖袭击等大型破坏性事件。该项目将研究 NG-MAN 的新颖弹性策略，其中包含新技术方向、技术和边缘计算。这项研究有可能在影响大都市地区的灾难场景中实现关键通信和服务的高可用性。 这个由美国国家科学基金会和日本国家信息通信技术研究所 (NICT) 联合资助的研究项目将为抗灾 NG-MAN 的设计提供新方法。主要研究领域有三个，旨在解决灾前阶段（即预防）和灾后阶段（即恢复）中出现的复杂网络管理和设计问题： i) NG-中的抗灾控制平面男人。将研究控制平面保护的新策略，目标是即使主控制器发生故障也能保持运行的认知和分层控制平面架构。 ii) NG-MAN 容灾数据平面的切片保护。应根据不同网络切片和相关服务的优先级，考虑组成切片必须受到保护的所有元素，即带宽、计算和存储资源，实施不同的灾难恢复方法。 iii) 通过可部署的恢复装置快速恢复。网络的灾后快速恢复至关重要，可以通过使用可移动设备来促进，例如通过专用卡车运输以恢复连接或计算设施。 （2011 年日本地震和海啸后部署了移动部队）。该项目将探索部署光突发模式放大器以恢复光纤设备的运行。 对拟议方法的评估将使用仙台的 NICT 测试台进行。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
