Title: How to Make TCP Fast in Future High-Frequency Wireless Networks?
Speaker: Artem Krasilov, IITP RAS, NRU HSE, MIPT.
Abstract: Wireless technologies continuously evolve providing higher data rates to end-users. To achieve multi-gigabit data rates, 5G and beyond systems will utilize ultra-wide channels available in high-frequency bands (e.g., mmWave, terahertz, and lightwave bands). In contrast to traditional low-frequency bands, these bands have unique characteristics connected with high signal attenuation and high blocking probability that lead to significant fluctuation of the wireless link capacity. The majority of existing applications, such as web browsers, social network clients, cloud storage, rely on the Transmission Control Protocol (TCP). TCP is a transport layer protocol responsible for selecting appropriate data transmission rate and providing reliable data delivery between end-points. In this talk, we will discuss in detail the performance issues arising when TCP operates over high-frequency wireless links and the causes of these issues. After that, we will consider various approaches aimed to improve TCP performance either proposed by the Internet Engineering Task Force (IETF) and the research community.
Bio: Artem Krasilov received his MS degree and Ph.D. degree in telecommunications from Moscow Institute of Physics and Technology in 2010 and 2013, respectively. Currently, he is a senior researcher at the Institute for Information Transmission Problems of the Russian Academy of Sciences (IITP RAS) and Higher School of Economics (HSE). He has been involved in various national and international research projects supported by both academic foundations (FP7 programme, Russian Government) and industrial partners. His professional interests are related to next-generation wireless networks, 5G, Wi-Fi, QoE/QoS provisioning in wireless networks, development of analytical and simulation tools for performance evaluation and optimization of different wireless access technologies. He has co-authored over 40 research papers.
The seminar is free and open.
