基于ICMP和SNMP的网络设备监测技术

Monitoring technology of network devices based on ICMP and SNMP

为了提高网络设备在线故障监测的准确性和实时性,结合指挥控制系统自身特点和现有监测方法,提出了一种在线监测方法和基于OLS(最小二乘)的自适应周期轮询改进算法。对改进的算法进行了仿真验证,仿真结果表明该算法在降低网络负载的基础上,能够提高超出阈值部分监测的灵敏度。实验结果表明,综合监测方法对于提高指挥控制系统网络及网络设备的可靠性具有重要意义。

To improve the accuracy of fault monitoring and real-time, a novel method based on the real state of Command and control system and existing online monitoring methods and an improved variable polling period arithmetic are proposed and the a- rithmetic is validated by simulation. The simulation results show that the algorithm reduces network load and can improve moni- toring sensitivity on the portion of exceeding the threshold. Experiments show that integrated monitoring methods for the net work maintenance and support of command and control system has a certain value.
