Packet Capture on Home Gateways: Is it feasible?

Abstract : Residential Internet access and home networks recently re- ceive a lot of attention from the research community, the reg- ulatory agencies, and ISPs. Home gateways provide Internet connectivity for increasing numbers of devices, serving several purposes such as telephony, media-streaming, data, or gaming. Thus, troubleshooting and monitoring home networks is fundamental to understand their problems and challenges. Since monitoring the home from an end-device is restricted in terms of what can be monitored, projects such as SamKnows (UK & US) rely on active measurements from the home gateway. In this paper, we want to explore the next step: Passive measurements on home gateways. We experimentally analyze resource consumption of running tcpdump capturing traffic forwarded by different home gateways. We find that it is feasible to do so for throughputs in the order of typical DSL access speeds. Yet, capturing fully loaded Fast Ethernet or faster links is more challenging.
