Bimonthly seminar

NewNet@Paris organizes bimonthly seminars in order to boost synergies between researchers of the chaire.  The seminar will take place:

  • every other Wednesday morning, from 10am to 12am  in Telecom ParisTech premises (23 av Italie, Room I304).
  • note that weekly  LINCS seminars are held on the same premises in the afternoon

The goal is to discuss on-going research and potential research collaborations
and opportunities. The seminar will consist of technical presentations and will be followed by information about the chair (News, Q&A).  The seminar is aimed to be:

  • open, to anyone interested from Cisco or Telecom ParisTech
  • informal, ideal for Ph.D students to present their work (even early work)

  • NewNet@Paris meeting

    March 29, 2017 @ 10:00 am - 12:00 pm

    Speaker: Dario Rossi
    Title: The web, the users, and the MOS: Influence of HTTP/2 on user experience

    Talk of the PAM'17 paper " The web, the users, and the MOS: Influence of HTTP/2 on user experience". The PAM conference is in the same week (https://research.csiro.au/pam2017/program/) , so we'll have the NewNet@Paris and the PAM talks about at the same time 🙂

    This is joint work with E. Bocchi (Telecom ParisTech — Politecnico di Torino), L. De Cicco (Politecnico di Bari), M. Mellia (Politecnico di Torino), D. Rossi (ENST).

    Paper abstract.
    This work focuses on the evaluation of Web quality of experience as perceived by actual users and in particular on the impact of HTTP/1 vs HTTP/2. We adopt an experimental methodology that uses real web pages served through a realistic testbed where we control network, protocol, and application configuration. Users are asked to browse such pages and provide their subjective feedback, which we leverage to obtain the Mean Opinion Score (\mos), while the testbed records objective metrics.

    The collected dataset comprises over 4,000 grades that we explore to tackle the question whether HTTP/2 improves users experience, to what extent, and in which conditions.
    Findings show that users report marginal differences, with 22\%, 52\%, 26\% of HTTP/2 MOS being better, identical, or worse than HTTP/1, respectively. Even in scenarios that favor HTTP/2, results are not as sharp as expected. This is in contrast with objective metrics, which instead record a positive impact with HTTP/2 usage. This shows the complexity of understanding the web experience and the need to involve actual users in the quality assessment process.
