大规模停电、海底电缆切断或互联网蠕虫等破坏性事件可能会导致互联网偏离其正常运行状态。这种偏离常态的现象，我们称之为互联网上的“冲击”，或“互联网地震”。由于互联网是一个庞大、复杂的移动目标，迄今为止，关于如何观察和量化对互联网的影响的成功研究很少，无论是在特定的事件期间还是在真实的时间。在本文中，我们设计了一个互联网地震仪，或I-seismograph，提供一个“里氏震级”的互联网。由于路由是Internet最基本的功能，而边界网关协议（BGP）是事实上的标准域间路由协议，因此本文重点研究了BGP。在定义了什么是“影响”的意思是相对于BGP，我们描述了如何I-seismograph测量的影响，验证其使用与几个破坏性事件，并进一步验证其准确性和一致性。我们表明，我们可以评估BGP的影响，在任意时期内，包括这样做在真实的时间。
Disruptive events such as large-scale power outages, undersea cable cuts, or Internet worms could cause the Internet to deviate from its normal state of operation. This deviation from normalcy is what we refer to as the “impact” on the Internet, or an “Internet earthquake.” As the Internet is a large, complex moving target, to date there has been little successful research on how to observe and quantify the impact on the Internet, whether it is during specific event periods or in real time. In this paper, we devise an Internet seismograph, or I-seismograph, to provide a “Richter scale” for the Internet. Since routing is the most basic function of the Internet and the Border Gateway Protocol (BGP) is the de facto standard inter-domain routing protocol, we focus on BGP. After defining what “impact” means with respect to BGP, we describe how I-seismograph measures the impact, exemplify its usage with several disruptive events, and further validate its accuracy and consistency. We show that we can evaluate the impact on BGP during an arbitrary period, including doing so in real time.
