Enhancement and analysis of TFRC performance for real-time data application: A survey

Abstract

In this project, we propose an enhancement and analysis of transport control protocol friendly rate control (TFRC) for real-time data application (audio/video). Traditionally, real-time data transmission has been accomplished over the user datagram protocol (UDP). The challenging issues of using transport control protocol (TCP) are restrictive bandwidth and lagging. Additionally, it is widely known that TCP is ill-suited to real-time multimedia streaming application. Having known these issues, this project aims to study the possibilities for analysis and improvement of real-time data application using TFRC which is designed for long-lived streams. As known, there are many advantages of TFRC, which are congestion control and guaranteeing the required throughput. Therefore, this project explores and proposes the advantages of TFRC in transmitting and receiving real-time data which currently uses UDP. It is proposed that the investigation of TFRC in real-time data is conducted using simulation technique. During the simulation, the developed model is representing the real-time application for analyzing the performance of modified TFRC. The simulation study of this project is to analyze and evaluate some of restraint issues for real-time data application to use TFRC. As a solution, a few suggestions are discussed to overcome stated problem and make comparison and evaluation, which are aimed to get results about better performance between enhanced TFRC and UDP in terms of streaming real-time data.
