We present the first empirical study of home network availability, infrastructure, and usage, using data collected from home networks around the world. In each home, we de- ploy a router with custom firmware to collect information about the availability of home broadband network connectivity, the home network infrastructure (including the wireless connectivity in each home network and the number of devices connected to the network), and how people in each home network use the network. Outages are more frequent and longer in developing countries sometimes due to the network, and in other cases because they simply turn their home router off. We also find that some portions of the wire- less spectrum are extremely crowded, that diurnal patterns are more pronounced during the week, and that most traffic in home networks is exchanged over a few connections to a small number of domains. Our study is both a preliminary view into many home networks and an illustration of how measurements from a home router can yield significant information about home networks.

This is joint work with Mi Seon Park, Srikanth Sundaresan, Sam Burnett, Hyojoon Kim, Nick Feamster. It will appear at IMC 2013.
