Abstract

In this contribution, we investigate the performance of the output buffer of a video streaming server. We assume that the server encodes the video stream in a scalable way. When the output buffer gets congested, one may choose to drop the transmission of some of the layers in the packets, thus reducing the packet transmission time and expediting the restoration of the buffer size to normal levels. A discrete-time finite capacity queueing model with buffer size dependent transmission times is constructed and analysed using a probability generating functions approach. We conclude with some numerical examples.
