A discussion of network fault diagnosis using Bayesian method

Bayesian Network is one of the most effective theoretical models for uncertainty knowledge expression and reasoning. In the paper, we simply discuss how to diagnose network fault using Bayesian network based on inference algorithm. This paper illustrates the construction of Bayesian network model for system and basic inference model of Bayesian network and instance. This paper raises an instance using inference model and illustrates inference algorithm based on bayesian network and emulation.
