在这里，我们揭示了跨欧洲天然气管道网络的负载和容错骨干。结合拓扑数据与信息的国家间流量，我们估计的全球网络的负载和它的容错故障。为了做到这一点，我们应用两个互补的方法广义介数中心和最大流。我们发现，天然气管道网络的增长，以满足双重目的。一方面，主要管道被大量的最短路径穿过，从而提高了网络的效率;另一方面，非操作管道对网络容量的影响很小，这意味着网络是容错的。这些发现表明，跨欧洲天然气管道网络是强大的，即，对高负载链路的故障具有容错能力。
Here, we uncover the load and fault-tolerant backbones of the trans-European gas pipeline network. Combining topological data with information on intercountry flows, we estimate the global load of the network and its tolerance to failures. To do this, we apply two complementary methods generalized from the betweenness centrality and the maximum flow. We find that the gas pipeline network has grown to satisfy a dual purpose. On one hand, the major pipelines are crossed by a large number of shortest paths thereby increasing the efficiency of the network; on the other hand, a nonoperational pipeline causes only a minimal impact on network capacity, implying that the network is error tolerant. These findings suggest that the trans-European gas pipeline network is robust, i.e., error tolerant to failures of high load links.
