Me

Welcome ! You should find all my info, posters, publications, presentations and so on on this website !

I got my Ms. C. in Computer Networks and Embedded Systems at the University of Strasbourg in 2019, working on OPTIC, an efficient BGP protection scheme that aims at effectively and optimaly protect transiting traffic from intra-domain failures while respecting hot-potato routing (master’s thesis, slides).

I am now working on my Ph. D. funded by a governemental fellowship at the University of Strasbourg, in the Networks Teams of the ICube laboratory. My work is on Segment Routing, path computation and network monitoring (which lead to the algorithm Best2Cop and its variants), and is supervised by Pr. Cristel Pelsser and Dr. Pascal Mérindol (publications below). Meanwhile, I continued to work on OPTIC (publications below as well). I also did several (2019/2020 - 2020/2021) complementary teaching activities.

Besides my work on Segment Routing, I also worked on Internet topology discovery, more precisely on hidden MPLS tunnels revelation in the wild (as always, publications below, code is here) and on large-scale multi-domain tunnels measurements (Geant GN4).

As you may have guessed, my main research interests are:

  • Routing and path computation
  • Network measurement and monitoring
  • Topology discovery
