Notification service event channel is sensitive to overload. The event channel may become overloaded during temporary traffic peaks when more requests arrive than the event service is designed for. We address the problem from the perspective: control the number of events entering the system to guarantee the performance. First, design the fuzzy-smith controller for the system. Fuzzy-smith control, which adopts fuzzy logic inference and rule base, is very effective for the large delay-time system and robust to the changes of system parameters. Then, apply the controller to the simulation and obtain the results. Finally, we compare the proposed fuzzy-smith control with the proportional integral smith (PI-smith) control by simulation. The results showed that the fuzzy-smith controller outperforms the PI-smith under such conditions that are different from the operating point chosen in the design
