This paper shows a methodology for user-driven, top down approach to research in quality of service issues in multimedia: systems. As a case study, we show a development of metrics, validation by means of a user study, and a performance evaluation of a prototyping environment. What is used, the Berkeley Continuous Media Toolkit (CMT) is a popular environment that satisfies this need. From a human user's perspective, in order for multimedia demonstrations to be comprehensible, the number of audio or video frames dropped and the timing delays in the ones that are displayed, need to be kept to a minimum. Therefore, it is important to know the frame dropping characteristics of CMT. In a series of experiments we monitored the variation of these parameters with respect processor and network loads. It was observed that loads affect aggregate frame drops at lower rates and consecutive frame drops at higher rates. Because at a higher rates a large number of consecutive frames are dropped, the ones that are played appear in a more timely manner. As a solution to observed problems, we present some QoS based approaches to control drop and delay parameters. |
