| Abstract: | According to the flow balance theorem and queuing theory, this paper, by adopting approximate solution techniques, conducts the qualitative analysis and study on cell scheduling strategies of priority class and obtains a better solution tallying with factual condition by deduction. The paper validates the results by simulation and numerical value computing. The work provides the theoretical reference for choosing scheduling strategies when broadband switches as well as routers are designed. And this is also of great significance in improving throughput and keeping QoS and services fairly functioning. |
