Interactive Multimedia Streaming Architecture

When the optimization goal of interactive multimedia streaming applications shifts to tail latency, the main contributors of latency are no longer the same as the contributors of median latency in the original architecture. In this chapter, we focus on analyzing where the end-to-end latency fluctuations come from in the existing interactive multimedia streaming architecture. We will analyze the reasons for latency fluctuations in general and then analyze the causes of latency fluctuations from the perspectives of the control path and data path.
