Abstract
In the vast majority of mobile applications, the Transmission Control Protocol (TCP) is still leveraged at the transport layer of the Internet’s protocol stack. But, in many cases, the performance of TCP over mobile networks has been proven sub-optimal in practice, thus causing substantial bottlenecks. Quick UDP Internet Connections (QUIC) is a new protocol, currently being standardized by the Internet Engineering Task Force (IETF), that aims at solving some of the inherent problems of TCP. The purpose of this paper is to provide a comprehensive overview of QUIC and compare the performance of QUIC and TCP in wireless networks. To compare QUIC with TCP under various transmission scenarios over LTE networks, the ns-3 network simulator has been employed. The simulations performed showed that 1) under good or average transmission conditions, QUIC is characterized by a better steady state throughput at the same time achieving quite lower file download times; and 2) under poor transmission conditions, the two protocols exhibit a similar performance.
Highlights
Ever since its creation, the Internet has experienced an impressive rise both in the number of users base and the volume of data traffic
1) Under good or average received signal quality at the User Equipment (UE), the QUIC protocol has a better steady state throughput performance compared to TCP
This indicates that fairness between TCP and QUIC does not exist, even when the radio resources at the Evolved Node B (eNB) are distributed to all the UEs. 3) QUIC demonstrates quite lower file download times compared to TCP, for all file sizes examined
Summary
The Internet has experienced an impressive rise both in the number of users base and the volume of data traffic. The report foresees that 1) the volume of IP traffic will be 235 Exabytes per month in 2021, that is three times the corresponding traffic in 2016; and 2) the number of Internet users is expected to reach 5.3 billion by the end of 2021. The majority of web applications today leverage TCP and Hyper Text Transport Protocol (HTTP) to perform functionalities, such as connection establishment, reliable data transmission and congestion control. The original design of TCP and HTTP did not predict the increasing complexity of modern web pages and the dynamic nature of Internet traffic. These protocols have an adverse effect on web access times, deteriorating the Quality of Experience (QoE) offered to the users
