寻找复杂网络的统一属性是一个热门的、具有挑战性的和重要的问题。对于将鲁棒性和脆弱性作为统一概念的建模方法，互联网是一个特别有吸引力的案例研究，主要是因为它的应用程序无处不在，无处不在，并且在每个细节层次上都存在广泛可用的论述。尽管如此，对互联网建模的其他方法往往会做出截然不同的假设，并对同一个系统的基本属性得出相反的结论。幸运的是，对互联网技术的详细了解与独特的网络测量能力相结合，意味着这些差异可以被彻底理解并明确解决。本文旨在使这一过程的最新结果超越互联网专家，向更广泛的科学界开放，并澄清基本方法学差异的几个来源，这些差异与互联网或这里重点讨论的两种具体方法（即，无标度网络和高度优化的容差网络）。
The search for unifying properties of complex networks is popular, challenging, and important. For modeling approaches that focus on robustness and fragility as unifying concepts, the Internet is an especially attractive case study, mainly because its applications are ubiquitous and pervasive, and widely available expositions exist at every level of detail. Nevertheless, alternative approaches to modeling the Internet often make extremely different assumptions and derive opposite conclusions about fundamental properties of one and the same system. Fortunately, a detailed understanding of Internet technology combined with a unique ability to measure the network means that these differences can be understood thoroughly and resolved unambiguously. This article aims to make recent results of this process accessible beyond Internet specialists to the broader scientific community and to clarify several sources of basic methodological differences that are relevant beyond either the Internet or the two specific approaches focused on here (i.e., scale-free networks and highly optimized tolerance networks).
