Performance Analysis of Discrete Time Polling Queuing System Based on Parallel Optimization Gated Service

Aiming at the problem of low efficiency of pipelined scheduling in system of periodic query gated service,this paper proposes a systematic service resource scheduling strategy based on parallel optimization gated service polling control.Firstly,the queuing system and its mathematical model are constructed.Moreover,after deriving the partial derivative of the probability generating function of the system state variables,the first and second order partial differential equations are solved.Finally the complete mathematical analytic expressions of the system performance parameters are derived.In this paper,the system is further verified by computer simulation experiments,and it is found that the statistical analysis results are consistent with the theoretical analysis results.The performance analysis shows that the queuing length and waiting delay characteristics of the polling system have been greatly improved,which can better adapt to the service requirements of delay sensitive data in dense data environment.
