Abstract: In an embodiment, a computer-implemented method for determining spans for network configuration dependencies is described. In an embodiment, the method comprises: receiving, by a central controller implemented in a computer network, graph data that represents a graph having nodes and first-type links. The nodes comprise first-type nodes, second-type nodes, and third-type nodes. A plurality of second-type links between a subset of the nodes is determined. For each first-type link, a first-type link between two nodes connected by the first-type link is removed if the two nodes are also connected by a second-type link. For each second-type node, a second-type node is removed and an incoming link and an outcoming link for the second-type node are concatenated. Initial spans and real spans for the first-type nodes and the third-type nodes are determined. For each first/second-type node, configuration messages are generated and transmitted according to a real-span determined for the node.
