It is exciting to work with some of the Internet infrastructure
network operators (e.g., China Mobile, Telefonica, T-Mobile) and application developers (e.g., Tencent).
- [June 2020] One main thread of my research is the
integration of applications and networks, and one major
deployment effort is the IETF ALTO standard. Please see
the
June 2020 IEEE Communications Standards Magazine News
for an update on ALTO.
- [February 25, 2020]
Our workshop,
"Network-Application Integration/Co-design (NAI) Workshop"
, has been accepted as a SIGCOMM'20 workshop.
Please do consider to submit to this workshop.
- [January 2, 2020]
I typically do not report news outside of my group, but this is an exception. Big Congratulations to the team of Enric Pujol, Ingmar Poese, Johannes Zerwas, Georgios Smaragdakis, and Anja Feldmann, for their
Steering Hyper-Giants' Traffic at Scale work (link to their paper), which won the CoNEXT 2019 Best Paper Award and the IETF/IRTF Applied Networking Research Prize 2020. The work starts with the ALTO protocol but goes well beyond, and reports on their multi-year experience in designing, building, rolling-out, and operating their large scale system which enables automated cooperation between one of the largest eyeball networks and a leading hyper-giant. This is much larger and longer than our
deployment work in Comcast reported in RFC 5632. Very impressive work!
