网络以各种方式相互作用。尽管网络之间增加的连接性往往会使系统更健壮，但如果网络之间存在依赖关系，这些系统极易受到随机故障或攻击。一个网络的损坏会导致另一个网络的损坏。这将导致连锁故障，放大原来的损害，并可能迅速导致整个系统崩溃。了解导致连锁故障的系统特性，并支持其继续传播是发展更强大的系统和缓解策略的重要一步。近年来，关于随机网络、簇网络和空间嵌入网络组成的系统的鲁棒性研究取得了一些重要成果，本文综述了连通性和依赖性在网络的网络鲁棒性中的作用。我们进一步讨论了相互依赖的网络上的级联故障的动态，包括级联寿命预测和驱动级联的拓扑性质的解释。
Networks interact with one another in a variety of ways. Even though increased connectivity between networks would tend to make the system more robust, if dependencies exist between networks, these systems are highly vulnerable to random failure or attack. Damage in one network causes damage in another. This leads to cascading failures which amplify the original damage and can rapidly lead to complete system collapse.Understanding the system characteristics that lead to cascading failures and support their continued propagation is an important step in developing more robust systems and mitigation strategies. Recently, a number of important results have been obtained regarding the robustness of systems composed of random, clustered and spatially embedded networks.Here we review the recent advances on the role that connectivity and dependency links play in the robustness of networks of networks. We further discuss the dynamics of cascading failures on interdependent networks, including cascade lifetime predictions and explanations of the topological properties which drive the cascade.
