Performance evaluation of video streaming using TFRC, modified TFRC over wired networks

Abstract

In the modern times we see that real time applications are increasing over the internet. Especially Multimedia streaming plays an important role in the Internet. These applications face congestion indication and reduce the reliability which is the major bottleneck in networks. So, streaming applications characterized by delay and bandwidth needs to get best effort in the network. Transmission Control Protocol (TCP) is not appropriated for the congestion problem in time-sensitive applications. TCP Friendly Rate Control protocol is an efficient rate control for streaming media applications in the wired network. The standard TCP-Friendly Rate Control (TFRC) with Additive Increase — Multiplicative Decrease (AIMD) schema wastes the bandwidth and it may react to congestion when the packet loss has occurred. So TFRC with Square Increase — Multiplicative Decrease (SIMD) schema implemented based on Real time Transport Protocol (RTP) which improves video streaming quality at receiver. The RTP rate based SIMD provides the better quality than standard TFRC. This gives better performance with respect to delay, frame lose ratio, jitter and improves the video quality than the standard TFRC protocol. The Simulation results indicate the comparison with UDP, TFRC, and RB-SIMD based TFRC protocols
