Delay-based Congestion Control Mechanism for Video Services - Mechanism including Backward Loading and Real-time Modes

Abstract

Currently the congestion control of the Internet is implemented through overprovisioning and TCP protocol. Unfortunately, TCP is not completely suitable for the use of video services. However, recent studies have shown that these video services represent over half of Internet traffic, with a growing trend. There are also arguments against massive overprovisioning. Due to these factors, there is a need to equip video services with proper congestion control. Unfortunately, most of the congestion control mechanisms developed for the use of video services can only offer low priority services or TCP-friendly real-time services. This paper provides a study in which a new delay-based congestion control mechanism is presented. This mechanism can offer congestion control services for both of these service types.
