[00:00:02.530]I'm working on the so-called TCP.
[00:00:04.850]TCP is a fundamental internet protocol.
[00:00:08.350]You are using TCP when you are checking emails,
[00:00:12.910]reading news, watching videos
[00:00:15.890]or uploading photos.
[00:00:18.000]We proposed a new TCP,
[00:00:21.080]it's called CUBIC TCP.
[00:00:23.140]by collaborating with two other universities.
[00:00:26.190]And now, the specification of our CUBIC TCP
[00:00:29.170]was accepted and published by IETF.
[00:00:33.030]This IETF is an international organization,
[00:00:35.920]that is in charge of the internet standard
[00:00:38.910]and specifications. So our CUBIC TCP
[00:00:42.520]can achieve a much better performance
[00:00:44.810]than the traditional TCP, and also the
[00:00:48.010]many other TCP protocols. And because of that,
[00:00:51.540]this CUBIC TCP has been adopted by
[00:00:54.680]all the major operating systems.
[00:00:57.280]Our long term goal is to make sure that
[00:01:00.090]we have not only a fast internet,
[00:01:03.530]but also a reliable internet that you can count on
[00:01:07.910]even in an emergency situation.
[00:01:10.595]Do you think like, too much is...
[00:01:13.530]I want to finish my PHD,
[00:01:17.840]so that I can have the ability to go back
[00:01:20.630]to my country and then teach other students
[00:01:23.040]in my country. So I learn a lot from him,
[00:01:26.360]and not only in terms of PC stuff,
[00:01:30.980]and then crosswords,
[00:01:32.990]but I also learn from him how to be a good advisor.
[00:01:37.030]The reason that I'm interested in this problem,
[00:01:39.100]and also excited about this problem, because this is
[00:01:42.210]something that you can see the impact of your work.
[00:01:46.310]So something that you designed and implemented
[00:01:48.960]has been used by almost all the internet users.
