Focus on some topics : cloud networkingCloud networking
Impact of virtualization layer (Vmware, Xen) on network performance
Delineating impact of CPU sharing, virtual switch, NIC virtualization, VM scheduling
Example of resultsA bug in … Linux kernel of TCP at high speed
lack of fairnessFinding the root was … complex
Focus on some topics: video over mobile networkVideo dominates traffic in mobile (3G/LTE)
networkStringent QoSQuestion for ISP (Orange): budget resources so
as to minimize cost while maintaining QoSProblems (non exhaustive list)
Video download is a complex function of (smartphone, OS, Videocaster (YT, Dailymotion, )
Minimizing Energy of Network In data center: networking 10 to 20% of the
total energy cost of data centers ISPChallenges addressed:
How to practically implement green routing? Trade-off energy/QoS for users How to efficiently simulate/evaluate?
Ns-3 extensions SDN (Software Defined Network) testbed to be
deployed in 2014 - joint effort with Coati
