摘要： 为提高故障检测所要求的实时性和高效性,对基于SNMP的故障轮询策略进行了研究和改进,提出了一种智能轮询算法,该算法能够根据网络设备性能参数值的变化,动态调节轮询间隔时间·通过仿真实验证明,与传统的等时间间隔轮询方式相比,智能轮询算法能更准确地刻画数据变化细节,有效地减小数据采集造成的失真,并能够合理利用网络带宽,上述优点在一系列实践中也得到了验证·

Abstract: In order to enhance the real-time operability and efficiency, which are both required for fault detection, the fault polling scheme based on SNMP is discussed and improved, thus presenting a new intelligent polling algorithm. This algorithm can dynamically adjust the intervals in accordance to the performance parameters of network equipment. Simulation results showed that the intelligent algorithm could display data in detail more accurately than the traditional equal-interval polling scheme such that the distortion in data collection can effectively be minimized with the network bandwidth used rationally. The above advantages have all been verified in practice.
