Dynamic Polling Scheme of Network Fault Management Based on Cloud Model

In order to enhance the real time operability and efficiency of polling which are both crucial for network fault management, the current network polling schemes based on SNMP are discussed, and a novel dynamic polling scheme is put forward. By soft partition of variation amplitude concept and uncertainty reasoning based on cloud model, this scheme realizes the fine dynamic adjustment of polling intervals according to the qualitative rules. Simulation results show that the proposed scheme can display data in detail more accurately, and the distortion in data collection can effectively be minimized with the network bandwidth used rationally.
