Hello all,
I am trying to understand networks etc and put some maths in it. Of course, real networks dont have a simple tree structure in order to use the simple probability calculation as they have to offer service 99.999...% so the structure turns out to be more like a graph. so let's say we have a node A that we want to keep as fault-free as possible and we have him connected to 2 hubs (the hubs are also connected between them). Hub 1 has links to node A and two other nodes which we dont care as much as node A, and Hub 2 has links to 3 nodes that we dont care again that much. so how can I calculate the probability of A failing in that simple structure?
