A facility is a group of links and/or nodes that are likely to fail together. It is used in failure simulations where accurate modeling requires the simultaneous failure of specific links and/or nodes. For instance, if several links travel over the same fiber, a fiber cut will break all of them at once. In this case, one can define a facility to represent the SRLG (Shared Risk Link Group) containing those links. Another example is the set of switches on one floor of a large data center, together with all the links going into or out of that floor.
