Abstract
We address the problem of diagnosing complex discrete-event systems such as
telecommunication networks. Given a flow of observations from the system,
the goal is to explain those observations by identifying and localizing
possible faults. Several model-based diagnosis approaches deal with
this problem but they need the computation of a global model which is
not feasible for complex systems like telecommunication networks.
Our contribution is the proposal of a decentralized approach which permits
to carry out an on-line diagnosis without computing the global model.
This paper describes the implementation of a tool based on this approach.
Given a decentralized model of the system and a flow of observations,
the program analyzes the flow and computes the diagnosis in a decentralized
way. We also present experimental results based on a real
system.
