Information détaillée : 


Christophe Diot received a Ph.D. degree in Computer Science from INP Grenoble in 1991. With INRIA Sophia-Antipolis (Oct 93-Sept 98), Diot pioneered diffserv, single source multicast, and peer-to-peer online games. At Sprint (Oct 98-Apr 03), he pioneered Internet measurements. Diot was with Intel Research from May 03 to Sept 05, and then joined Thomson where he started two research labs: Paris in 2006 and Palo Alto in 2011. Diot's research activities now focus on content delivery architectures and personalization. Diot has around 40 patents and more than 300 publications in major conferences and journals. Thomson became Technicolor in January 10. Diot is currently Chief Scientist at Technicolor. He is an ACM fellow.

Résumé : 

ISPs #1 problem is home network troubleshooting, with WiFi related questions causing a large majority of the complains. Together with a major European NSP, Technicolor, who is providing home gateways (HGWs) to many broadband and cable service providers worldwide, has launched a new initiative to diagnose home network problems from the operational HGW. 

The talk will describe this effort (platform, and early observations) and show how we manage to (1) track performance problem in home networks and (2) infer personal information from purely technical data such as traffic counters, IP addresses, ARP tables.
