Performance Analysis of the First-order Characteristics of Two-level Priority Polling System Based on Parallel Gated and Exhaustive Services Mode

Aiming at the problem of how to ensure high quality network service requirements and user experience effects under the condition of limited network bandwidth resources, based on the priority polling architecture and parallel scheduling, this paper proposed a new system of two-class priority polling based on parallel optimization gated and exhaustive service mode. The system optimizes the service process and the conversion query process in parallel, which changes the pipeline operation mode of the traditional polling system and improves the overall efficiency of the polling system. The queuing system and mathematical analysis model are constructed according to queuing theory and stochastic process. After the derivation process of the first-order derivation, some complete expressions of the first-order characteristics are obtained, such as the mean queue length and mean cyclic period. Furthermore, computer simulation experiments are carried out, and the experimental results show that they are consistent with the theoretical calculations. System performance analysis shows that the mean queue length and mean cyclic period of the system have been significantly improved, which can better adapt to the requirements of high-quality network services under limited service resources.
