DESCRIPTION:Assessing the energy consumption or carbon footprint of intern
 et services is usually carried out through energy or carbon intensity figu
 res (in Wh or gCO2e per GB). In this talk\, I will first review the reason
 s why such approaches are likely to lead to misunderstandings and potentia
 lly to erroneous conclusions.  To overcome those shortcomings\, we introdu
 ce a new methodology to assess the impact of a given internet usage on the
  network infrastructure. The use case in this talk will video on demand. T
 he core of the method is a simplified network\, which is automatically sca
 led according to peak usage needs. This modeling is used to compare the po
 wer consumption of this infrastructure under different scenarios\, ranging
  from a sober baseline to a generalized use of high bitrate videos.\n\nAur
 élie Bugeau is a full professor in computer science at University of Bord
 eaux and a member of the French National Institute (IUF) Her primary resea
 rch area is image processing and analysis. Since few years\, she also stud
 ies environmental impacts of ICT.
