随着网络技术的发展,如何有效地进行网络管理的问题日益突出。故障管理是网络管理的核心内容。该文通过对简单网络管理协议SNMP中管理信息传输的轮询控制方式进行了分析,提出了一种新的轮询算法,采用嵌入马尔可夫链和概率母函数的分析方法,给出了轮询算法的数学模型。通过理论计算和仿真实验验证了新的算法提高了网络故障管理的效率。
With the development of network technology, how to efficiently manage network becomes outstanding and especially fault management is crucial. This paper analyzes the polling scheme based on SNMP, and proposes a new algorithm for polling system. By the embedded Marker chain theory and the generation function method, the mathematic model is explicitly obtained. Theoretical analysis and simulation results demonstrate the efficiency of new algorithm.
