Using Feedback Control for Notification Service Overload Protection

Notification Service is increasingly being used in a wide variety of distributed computing systems. One problem with Notification Service is that it is sensitive to overload. By analyzing the simulation results of the performance of current Notification Service, we find that the Notification Service needs overload protection. Thus a feedback control based overload protection of Notification Service is presented and designed. Experimental results show that this mechanism can control the load and achieve performance guarantees in the presence of load unpredictability, and it can also ensure allocating and utilizing system resources reasonably and efficiently.
