Abstract

ABSTRACT Data communication networks have large importance for the immediate post-earthquake emergency management and community resilience. In this study, the framework of simulation-based probabilistic seismic risk analysis of data communication infrastructure is applied to the real case of the inter-university data network of the Campania region (southern Italy). The network is constituted by point-like facilities (racks located within buildings and containing the device routing and managing traffic) and distributed links (buried fiber optic cables). The seismological, geological, and geotechnical features of the region were characterized together with the seismic vulnerability of each element of the network. The network performance is quantified in terms of traffic loss before and after the seismic event. Results are provided in terms of annual rate of events exceeding traffic loss thresholds and allow to identify the portion of the network mostly contributing to the seismic performance.

数据通信网络的地震危险性分析

摘要数据通信网络对地震后应急管理和社区恢复能力具有重要意义。在本研究中，基于模拟的数据通信基础设施概率地震风险分析框架被应用于坎帕尼亚地区（意大利南部）大学间数据网络的真实案例。该网络由点状设施（位于建筑物内的机架，包含设备路由和管理流量）和分布式链路（埋地光纤电缆）组成。对该地区的地震学、地质和岩土工程特征以及网络各要素的地震脆弱性进行了表征。根据地震事件前后的流量损失来量化网络性能。根据超过交通损失阈值的年事件率提供结果，并允许识别网络中对地震性能最有贡献的部分。

期刊介绍： Sustainable and Resilient Infrastructure is an interdisciplinary journal that focuses on the sustainable development of resilient communities. Sustainability is defined in relation to the ability of infrastructure to address the needs of the present without sacrificing the ability of future generations to meet their needs. Resilience is considered in relation to both natural hazards (like earthquakes, tsunami, hurricanes, cyclones, tornado, flooding and drought) and anthropogenic hazards (like human errors and malevolent attacks.) Resilience is taken to depend both on the performance of the built and modified natural environment and on the contextual characteristics of social, economic and political institutions. Sustainability and resilience are considered both for physical and non-physical infrastructure.
