Abstract This thesis analyzed the significance of prognostic and health management (PHM) in network
maintenance support. The key technologies of network PHM: management mechanism, health evaluation,
prognostic, fault localization, fault recognition and health management were emphatically discussed. Prob-
lems in key technologies of recent network PHM were summarized while the future developing trends were
introduced. Based on these analyzes, the thesis proposes a hierarchical distributed structure on mobile
agent and an integrated management framework for the network PHM system.
Keywords network; prognostic and health management; hierarchical distributed; mobile agent
