认识到宽带的重要性日益增加，一些政府已经开始大规模地努力从终端用户家中的设备测量宽带服务。这些研究的参与者是根据被认为与服务性能相关的先验特征（如地理区域、接入技术和订阅级别）选择的。此后的每一次新年部署都遵循相同的模式，确保测量点的数量在自然流失的情况下保持稳定。在本文中，我们开始探讨在住宅宽带网络中的Vantage位置选择的问题，利用FCC宽带美国研究的一部分收集的公开数据集。我们提出了第一次分析的边缘网络的性能变化和个人的Vantage点的多样性。我们探索这种多样性的根本原因，通过因素分析的背景因素，如用户的地理位置在ISP。该分析的目标是为正在进行的研究中的其他部署提供信息，并指导未来宽带网络调查的设计和部署。
In recognition of the increasing importance of broadband, several governments have embarked on large-scale efforts to measure broadband services from devices within end-user's homes. Participants for these studies were selected based on features that, a priori, were thought to be relevant to service performance such as geographic region, access technology and subscription level. Every new-year deployment since has followed the same model, ensuring that the number of measurement points remains stable despite the natural churn. In this paper, we start to explore the issue of vantage point selection in residential broadband networks by leveraging the publicly available datasets collected as part of the FCC Broadband America study. We present the first analysis of the variation of performance in edge networks and diversity of individual vantage points. We explore the underlying causes of this diversity through a factor analysis of contextual factors within an ISP such as the geographic location of subscribers. The goal of this analysis is to inform additional deployments in ongoing studies, and guide the design and deployment of future investigations into broadband networks.
