Abstract(in English) | In order to evaluate the quality of service (QoS) of video streaming services, most of previous work has focused on the analysis of the frame-level loss probability, or the recovery performance of forward error correction (FEC). However, the frame-level delay has not been studied due to analytical difficulty. In this paper, we analyze approximately the frame-level delay. Focusing on an output port of a bottleneck router, in which a video-packet flow and background traffic are multiplexed, we model it as a single-server queue with two independent inputs and an infinite buffer. We analyze the sojourn time of a block consisting of a group of packets, which is equivalent to a frame. We also conduct Monte Carlo simulation for estimating the mean block-level delay of the system with a finite buffer. We compare analytical and simulation results in order to validate the analytical model. It is shown from numerical examples that the difference between analysis and simulation significantly depends on the buffer size. It is also shown that the analytical model is useful when the buffer size is moderately large. |
