A computer-implemented method for filtering, responsive to a logical specification of a network farm and a communication model for the farm, a tree topology network specification to obtain a filtered tree topology network specification is disclosed. The filtered tree topology network specification has fewer devices therein relative to the tree topology network specification, devices needed for constructing the farm being available in the filtered tree topology network specification. The method includes removing a first set of devices and a first set of switching elements from the tree topology network specification starting at the lowest level of the tree topology network specification and working toward the root node of the tree topology network specification. Each device in the first set of devices represents one of a redundant device, a device having a type unneeded by the farm, and a device unavailable for constructing the farm. Each switching element in the first set of switching elements represents a switching element whose children devices are all members of the first set of devices.
