物理网络抗震空间设计
Spatial Design of Physical Network Robust against Earthquakes
摘要：
本文分析了物理网络的抗震能力，并提出了空间网络设计规则，使网络对地震的鲁棒性。使用的灾区模型是相当通用和有界的。建议的物理网络设计规则包括：（i）较短的Z字形路线可以降低网络与灾区相交的概率，（ii）如果路线长度是固定的，则附加性能度量（诸如修理成本）与网络形状无关，以及（iii）环形网络内的附加路由不会降低给定节点对之间的所有路由与灾区相交的概率，但较宽的迂回路由会降低它。文中还导出了计算两个给定节点断开概率的公式。最佳的服务器布局所示的理论结果的应用。这些分析结果通过经验地震资料得到了验证。
英文摘要：
This paper analyzes the survivability of a physical network against earthquakes and proposes spatial network design rules to make a network robust against earthquakes. The disaster area model used is fairly generic and bounded. The proposed design rules for physical networks include: (i) a shorter zigzag route can reduce the probability that a network intersects a disaster area, (ii) an additive performance metric, such as repair cost, is independent of the network shape if the route length is fixed, and (iii) additional routes within a ring network does not decrease the probability that all the routes between a given pair of nodes intersect the disaster area, but a wider detour route decreases it. Formulas for evaluating the probability of disconnecting two given nodes are also derived. An optimal server placement is shown as an application of the theoretical results. These analysis results are validated through empirical earthquake data.
