Abstract
This chapter discusses congestion control for video streaming applications. With the explosion in video streaming traffic in recent years, there arose a need to protect the network from congestion from these types of sources and at the same time ensure good video performance at the client end. The industry has settled on the use of TCP for transmitting video even though at first cut, it seems to be an unlikely match for video’s real-time needs. This problem was solved by a combination of large receive playout buffers that can smoothen out the fluctuations caused by TCP rate control and an ingenious algorithm called HTTP Adaptive Streaming (HAS) or Dynamic Adaptive Streaming over HTTP (DASH). HAS runs at the client end and controls the rate at which “chunks” of video data are sent from the server, such that the sending rate closely matches the rate at which the video is being consumed by the decoder. This chapter describes the work in this area, including several ingenious HAS algorithms for controlling the video transmission rate.
