有效减小时延的自适应p-坚持CSMA协议研究
Research of adaptive p-persistent CSMA protocol for reducing delay
摘要
Abstract
According to some real time sensitive network require for common data throughput, an adaptive p persistent CSMA/CD protocol for reducing the delay effectively is proposed. Firstly, the monitoring variables reflecting the network status will be found out, based on the monitoring values, the network status is classified into four types, the light load sta-tus, the relative light load status, the relative heavy load status and the heavy load status. Then the sending possibility p and the maximum back-off threshold Bm will be adjusted dynamically based on the judged network status. Finally, the delay and throughput and bus utilization of networks are simulated. The result shows that the adaptive p persistent CSMA/CD protocol can effectively reduce delay and jitter.关键词
