许多努力致力于增加对复杂和不断发展的互联网生态系统的理解。互联网交换点（IXP）是自治系统（AS）实现对等协议进行流量交换的共享基础设施。近年来，IXP已经成为越来越多的研究目标，因为它们代表了互联网多样性的一个有趣的缩影和提供最终用户服务的战略Vantage。在本文中，我们分析了最大的一组公共IXP在一个国家，即在巴西的IX.br项目。我们的深入分析基于来自所有玻璃服务器的BGP数据，并从全国范围的角度深入了解每个IXP的对等网络生态系统。我们提出了一种新的对等连接的亲和力度量非常适合测量不同类型的AS之间的连接。我们发现IX.br的对等密度值低于更成熟的生态系统，如AMS-IX、DE-CIX、LINX和MSK-IX。我们的最后一个贡献是共享15 GB的数据集沿着所有支持代码。
Many efforts are devoted to increase the understanding of the complex and evolving Internet ecosystem. Internet eXchange Points (IXP) are shared infrastructures where Autonomous Systems (AS) implement peering agreements for their traffic exchange. In recent years, IXPs have become an increasing research target since they represent an interesting microcosm of the Internet diversity and a strategic vantage point to deliver end-user services. In this paper, we analyze the largest set of public IXPs in a single country, namely the IX.br project in Brazil. Our in-depth analyses are based on BGP data from all looking glass servers and provide insights into the peering ecosystem per IXP and from a nation-wide perspective. We propose a novel peering affinity metric well-suited to measure the connectivity between different types of ASes. We found lower values of peering density in IX.br compared to more mature ecosystems, such as AMS-IX, DE-CIX, LINX, and MSK-IX. Our final contribution is sharing the 15 GB dataset along all supporting code.
