NeTS: JUNO2: Disaster-Resiliency Strategies for Next-Generation Metro Optical Networks

需要新一代的城域光纤网络来实现未来的“智能城市”的愿景，在这种网络中，城市居民可以访问一类革命性的超可靠和低延迟的网络服务，如自动驾驶、增强现实和远程医疗。城域网络将从单纯为收集最终用户流量而设计的僵化基础设施演变为提供应用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，下一代城域网络(NG-MAN)的设计必须能够应对重大破坏性事件，如自然灾害或恐怖袭击。该项目将为NG-MAN研究新的弹性策略，其中包括新的技术方向、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情景中实现关键通信和服务的高水平可用性。这项由国家科学基金会和日本国家信息与通信技术研究所(NICT)资助的联合研究项目将为抗灾NG-MAN的设计提供新的方法。为了解决在灾前阶段(即预防)和灾后阶段(即恢复)出现的复杂网络管理和设计问题，有三个主要研究领域：i)NG-MAN中的容灾控制平面。将研究控制平面保护的新策略，目标是一种认知和分层控制平面架构，即使主控制器发生故障，该架构仍可运行。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，考虑组成必须保护的切片的所有元素，即带宽、计算和存储资源，实施不同的灾难恢复方法。三)通过可部署的恢复单元实现快速恢复。网络的灾后快速恢复至关重要，通过使用可移动设备(例如，通过专用卡车运输以恢复连接或计算设施)来促进网络恢复。(2011年日本地震和海啸后部署了机动部队)。该项目将探索部署光突发模式放大器，以恢复光纤工厂的运行。对提议的方法的评估将使用仙台的NICT试验台进行。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
