These requirements are application specific and as far as protocol stacks are concerned, they are layer specific. It is essential to satisfy these requirements at all the system components along the path from a service provider to a service user, starting from and ending at the end points. It is equally important to develop methods to translate QoS requirements of an application into QoS parameters at different layers as well as implement architectures for the global management of QoS. This thesis includes an analytical study of buffer and jitter requirements in the transmission of digital video as well as an experimental study of QoS requirements and QoS mapping for the transmission of MPEG-2 video over IP-based networks and Ethernet in particular. First, we have examined the buffer constraints of the video server and the video clients in a video on demand system and found the constraints on the channel rate in order to avoid buffer overflow and/or underflow.
