QoS profile for performance aspect validation using VoD case study

As networked multimedia systems have evolved over the recent years, sophisticated multimedia applications have emerged. Through this,. It is now widely recognized that the non-functional or extra-functional properties of multimedia system are at least as important as its some what more classical functional properties and that they must considered as early as possible in the development life cycle in order to avoid costly failures. A revolution in the transmission of multimedia information over wired and wireless communication technologies has transpired, Society is now becoming more dependent on such technologies, and these are used in almost every aspect of our daily lives, including: communications, entertainment, education, marketing, research, health and medicine. To provide the user with effective experience in using these networked multimedia applications, it is imperative that optimum Quality of Service (QoS) is delivered. This requires innovative solutions for QoS management. These solutions need to employ better Human Computer Interaction (HCI) techniques and bridge the current gap between the user requirements and the system functionality. In our paper, we have applied the new QoS profile “the proposed QoS profiles for performance aspect of multimedia application”.[6] to test applicability and validity of such proposed QoS profiles and sub-profiles ,in which this[6] paper define standard QoS modeling elements related to performance aspect that capture the common features of all types of multimedia applications, modified the conceptual model[8] to be more applicable and effective for the design multimedia applications , and embedding those notations to UML notation since UML is considered the de-facto standard for object oriented analysis, visualizing, specification, design, documentation, then we tested there generality on Video On Demand case (VoD), and argue the advantage of standardization.
