Abstract
A network topology design system to determine placement of a set of controllers within a network with a split architecture, the placement of the set of controllers selected to minimize disruption of the split architecture network caused by a link failure, a switch failure or a connectivity loss between the set of controllers and the data plane components. The system performs a method including graphing a topology of the split architecture network, determining a set of clusters of nodes within the graph by applying an agglomerative clustering process or a partitive clustering process, determining, a centroid for each cluster in the set of clusters, assigning one of the set of controllers to each network element corresponding to a determined centroid in the graph, and assigning each controller to control a set of network elements corresponding to a cluster in the graph.
