Re: Your opinion on network analysis in the presence of uncertain events

I know of none that take probabilities as inputs. Traditional network simulators, such as GNS3, let you model various 
failure modes, but probability seems squishy enough that I don’t see how it can be accurate, and thus helpful. It’s 
like that Dilbert cartoon where the pointy haired boss asks for a schedule of all future unplanned outages :)

I took the survey. It’s short and sweet — well done!

Thanks a lot, Mel! Highly appreciated!

I do have a question. You ask "Are there any good?” Any good what?

I just meant whether existing network analysis tools were any good (or good enough) at reasoning about probabilistic 
behaviors that people care about (if any).

All the best,
Laurent
