Boolean Inference makes it possible to observe the congestion status of end-to-end paths and infer, from that, the congestion status of individual network links. ...

Moreover, since Boolean Inference is an ill-posed problem, no algorithm can solve it exactly (identify the congested links E c (t) without false negatives or positives) for any P c (t). ...

We formally prove that, under certain well defined conditions, network tomography works when links are correlated, in particular, it is possible to identify the probability that each link is congested ...
There are several practical scenarios in which this can happen; for instance, if we know the network topology at the IP-link or at the domain-link level, then links from the same local-area network or ...
