Fuzzy controller design for proportional loss differentiation services

The quality of services is one of the most important issues of today's internet. The programs and the different internet users' quality of services are different from one another. Varieties of methods have been presented in providing the internet's quality of services. The Proportional Differentiated services method is one of the newest ways of providing quality of services. In this essay, a proper fuzzy model for providing quality of services in the relative differentiated services is presented. The presented method is based on the JOBS method which is one of the newest methods of services differentiation. The suggested model is implemented and analyzed in ns2 simulation environment. The final results of this simulation reveal the superiority of the suggested fuzzy method compared with the non-fuzzy one.
