Et (smart) phone home!

Abstract

Most home users are not able to troubleshoot advanced network issues themselves. Hours on the phone with an ISP's customer representative is a common way to solve this problem. With the advent of mobile devices with both Wi-Fi and cellular radios, troubleshooters at the ISP have a new back-door into a malfunctioning residential network. However, placing full trust in an ISP is a poor choice for a home user. In this paper we present Extra Technician (ET), a system designed to provide ISPs and others with an environment to troubleshoot home networking in a remote, safe and flexible manner.
