Abstract: The current Internet delivers most data packets to their destinations with no options on delivery time. Considering that even parcel services offer a wide range of delivery time options from one day delivery to no rush delivery, it is obvious that the current Internet is insufficient in meeting the needs from diverse network services, thus impeding the emergence of futuristic network services. This talk introduces my ongoing journey in providing the Internet the ability to control the data delivery time with the objective of enabling both extremes: delay-tolerant networking and low- latency networking. According to its timeline, this talk visits various research topics such as human mobility modeling and mobility-driven data offloading on the first extreme; cellular bufferbloat mitigation and low-latency congestion control on the second extreme. Envisioning the unified framework bringing both extremes to the Internet concludes this talk.

Short Bio: Kyunghan Lee received his B.S., M.S., and Ph.D. degrees from the department of electrical engineering at KAIST (Korea Advanced Institute of Science and Technology), Daejeon, South Korea, in 2002, 2004, and 2009, respectively. He is currently an associate professor in the school of electrical and computer engineering at UNIST (Ulsan National Institute of Science and Technology), Ulsan, South Korea where he has led mobile systems and networking lab since 2012. His research interests include low-latency networking, mobile machine learning, context-aware networking, and opportunistic networking. He received two IEEE ComSoc William R. Bennett Prize in 2013 and 2016, given to an influential original paper published in the IEEE /ACM Transactions on Networking in the previous three years. He has served on the program committee of several major conferences such as IEEE INFOCOM , ACM MobiSys, and ACM MobiHoc; and has also served on the organizing committee of ACM MobiSys, IEEE SECON , and IEEE MDM ; and is serving as an area editor of Computer Networks.
