Adaptive RTP Rate Control Method

- 18 Jul 2011

- pp 7-12

TL;DR: This paper presents an adaptive method for maximizing network bandwidth utilization for the real-time applications that employs a PID controller that keeps the RTP packet loss fraction at a predefined reference point.

Abstract: In this paper, we present an adaptive method for maximizing network bandwidth utilization for the real-time applications. RTP protocol is chosen as the transport protocol and the network utilization is provided by increasing and decreasing the transmission rate of the RTP traffic. Our method employs a PID controller that keeps the RTP packet loss fraction at a predefined reference point. Packet loss fraction parameter is gathered from the RTCP receiver reports and fed into the PID controller that controls the transmission rate of the RTP traffic. Simulations are performed to demonstrate the effectiveness of the method under a bottleneck network configuration with background UDP traffic competing against the RTP traffic for the available bandwidth.
