Router Support for Better Video Transmission
Jae Chung, Mark Claypool · 2000
Multimedia streaming is difficult on the Internet, especially for video due to the large frame size and inter-frame dependencies resulted from high compression rates. This paper shows that router support for priority-based queue management could significantly improve performance of video streaming. We extend Rate-Based RED (Rb-RED) to Rate-Based RIO (Rb-RIO) which support three priority classes and apply it to MPEG. The performance mechanism on the video streams is measured, analyzed and compared with RED in terms of transport layer throughput, video stream quality and system fairness through simulation using NS. The study shows that Rb-RIO improves MPEG video stream quality and network system fairness.
