Abstract: This paper discusses the basic theory of the DiffServ algorithm, sets up the simulate model based on the OPNET network simulator. It collects the simulation results by simulating the DiffServ algorithm. From analysis of the results, the effect on the performance of QoS is researched by setting different service level.
