Crowdsourcing ISP Characterization to The Network Edge
Evaluating and characterizing Internet Service Providers (ISPs) is critical to subscribers shopping for alternative ISPs, companies providing reliable Internet services, and governments surveying the coverage of broadband services to its citizens. Ideally, ISP characterization should be done at scale, continuously, and from end users. While there has been significant progress toward this end, current approaches exhibit apparently unavoidable tradeoffs between coverage, continuous monitoring and capturing user-perceived performance. In this paper, the authors argue that network-intensive applications running on end systems avoid these tradeoffs, thereby offering an ideal platform for ISP characterization.
