Abstract: Based on establishing the mathematical model of the system and defining the parameters, using the embedded Markov chain and probability generating function as Probabilistic methods, the discontinuous-time, two-queue different gated polling system has been fully analyzed, the low-and higher-order properties and cycle period of the system are deduced, and the average queuing length and average waiting delay of information packets are calculated accurately. The simulation experiments agree well with the theoretical calculations. The analysis further deepens the cognition of the asymmetric threshold polling system, lays a foundation for research on the asymmetric threshold polling system, and has a positive significance for a better and more flexible control polling system.

Key words: asymmetric, dual-queue, Periodic Query, gated polling system, two-order property, average waiting delay
