【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 can 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.更多还原
