A technique for reducing the computational complexity for discriminating the existence of a communication path in a lattice communication network control system includes the steps of: checking for an existence of an alternate path between the two terminal nodes of a link, when a failure occurs in a link; and in the presence of the alternate path, setting the link to a failure state based on a consideration that there is a substitute path for the link, or in the absence of the alternate path, setting the link to an unconfirmable state out of the control of a management node, considering that a network is divided into two separate parts.
