Aiming at improving the working efficiency and resource utilization of the polling control system, this paper proposed a limited ( K = 2 ) polling control system for the site dormant activity state, and studied the mathematical model of the system by using the probabilistic parent function and the embedded Markov chain method. The simulation results show that the theoretical value is approximately equal to the experimental value, which indicates that the analysis method is correct and reasonable. Based on the limited ( K = 2) policy, the system serves the server according to the state of the dormant activity of the site. It used the qualified (K =2) service policy to ensure that the fairness of the system is not impaired, and distinguishing the dormant activity state of the site avoids the service to the dormant site without information packets. Compared with the existing service strategy, the system performance is significantly improved. [ABSTRACT FROM AUTHOR]
