摘要
为了提高车辆监控通信服务器的性能,根据其设计原理抽象出了一种网络节点的缓冲排队模型,运用马尔可夫链和排队理论推导计算了模型的平均队长和时延.在此基础上,对各参数在不同情况下对服务器性能的影响程度进行了详细的分析,提出了几种在不同拥塞条件下提高服务器性能的方法,并对各方法的优劣进行了对比.试验、仿真结果证实了所采用的模型和分析方法是正确有效的.
To improve the performance of a communication server for monitoring large-scale fleets, a queueing model is constructed based on the servers design principles. Markov chain and queueing theory are used to compute the model. Then this paper studies how the parameters act on the servers performance, and presents several schemes that might be used to improve the server. Base on the comparison, the paper proposes when and how to apply these schemes. Test and simulation have confirmed the validity of the model and analysis.
