ABSTRACT

When purchasing home broadband access from Internet service providers (ISPs), users must decide which service plans are most appropriate for their needs. Today, ISPs advertise their available service plans using only generic upload and download speeds. Un-fortunately, these metrics do not always accurately reflect the vary-ing performance that home users will experience for a wide range of applications. In this paper, we propose that each ISP service plan carry a "nutrition label" that conveys more comprehensive informa-tion about network metrics along many dimensions, including vari-ous aspects of throughput, latency, loss rate, and jitter. We first jus-tify why these metrics should form the basis of a network nutrition label. Then, we demonstrate that current plans that are superficially similar with respect to advertised download rates may have differ-ent performance according to the label metrics. We close with a discussion of the challenges involved in presenting a nutrition label to users in a way that is both accurate and easy to understand.

    • "An imminent technical and usability challenge is to summarize access network performance data so that users can make informed choices about the service plans that are most appropriate for them (akin to a " performance nutrition label "[2]). Our recent work proposes some first steps in this direction[22]. Lesson 3 (Home Network Equipment Matters) A user's home network infrastructure can significantly affect performance. "

    ABSTRACT: We present the results from the first study of Internet access link performance measured directly from home routers. In conjunction with the Federal Communication Commission's study of broadband Internet access in the United States, we investigate the throughput and latency of network access links from about 4000 routers across eight ISPs. Our findings provide a snapshot of access network performance across the United States, offer insights on how access network performance should be measured and presented to users, and inform various ongoing efforts to evaluate the performance of access networks around the world.

    • "One approach might be to map these low-level performance metrics to more meaningful application performance metrics. For example , researchers have proposed a nutrition label that presents more user-centric metrics that are derived from low-level metrics [51]. For example, a typical user may have difficulty understanding how packet loss can introduce severe performance degradations in voice stream; on the other hand, one might imagine profiling a user or household to identify the common applications used in the home, and presenting a report for the performance of each of those applications , based on the observed the low-level metrics (e.g., Skype performance may be poor, without necessarily telling the user it is because packet loss is higher than the application expects.)

    ABSTRACT: Managing a home network is challenging because the underlying infrastructure is so complex. Existing interfaces either hide or expose the network's underlying complexity, but in both cases, the information that is shown does not necessarily allow a user to complete desired tasks. Recent advances in software defined networking, however, permit a redesign of the underlying network and protocols, potentially allowing designers to move complexity further from the user and, in some cases, eliminating it entirely. In this paper, we explore whether the choices of what to make visible to the user in the design of today's home network infrastructure, performance, and policies make sense. We also examine whether new capabilities for refactoring the network infrastructure - changing the underlying system without compromising existing functionality - should cause us to revisit some of these choices. Our work represents a case study of how co-designing an interface and its underlying infrastructure could ultimately improve interfaces for that infrastructure.

    ABSTRACT: We present the first study of network access link performance measured directly from home gateway devices. Policymakers, ISPs, and users are increasingly interested in studying the performance of Internet access links. Because of many confounding factors in a home network or on end hosts, however, thoroughly understanding access network performance requires deploying measurement infrastructure in users' homes as gateway devices. In conjunction with the Federal Communication Commission's study of broadband Internet access in the United States, we study the throughput and latency of network access links using longitudinal measurements from nearly 4,000 gateway devices across 8 ISPs from a deployment of over 4,200 devices. We study the performance users achieve and how various factors ranging from the user's choice of modem to the ISP's traffic shaping policies can affect performance. Our study yields many important findings about the characteristics of existing access networks. Our findings also provide insights into the ways that access network performance should be measured and presented to users, which can help inform ongoing broader efforts to benchmark the performance of access networks.
