This paper proposes a method for evaluating network systems based on delay-jitter analysis using generalized stochastic Petri nets (GSPN). Systems are modeled by GSPN and tagged client approach. The mean delay time and its variance for systems are calculated by using equations derived from a Markov chain of the GSPN model. Systems can be evaluated statistically by the obtained values.Show More
We describe the design of a group synchronization mechanism for a local area network virtual environment and introduce a step synchronization mechanism. We use a football game to evaluate this mechanism. In this football game, users can share a virtual space where they can move around, dribble and shoot. To achieve synchronization among users, a client of the game exchanges data through a server w...Show More
Several probability distribution functions such as exponential distribution function have been used to represent the task arrival process and processing time of tasks for multimedia systems. These distribution functions are simple, memory less, and easy-to-use, however,they are difficult to represent the task arrival process of multimedia stream data or audio data having real-time properties. This...Show More
