… on the resilient controller placement to enhance the resilience of the control plane (dealing
with controller node failures). The authors in [13] studied the controller placement using the …

… In this paper, we compare placements using node-tocontroller latency, for the fundamental
limits … for other failure modes such as controller failure or disconnection. One could place …

… of nodes to one of the controllers in any arbitrary double link or node failure scenario. However…
Initially, we do not consider link failure and place the controller on nodes 1 to minimize the …

… In this paper, we propose a controller placement strategy for multiple link failures, … node
positions for controller placement. However, we can not neglect the failure of the controller…

… controller placement problem generally exploit methods to find out the best k nodes in a
network to place controllers … trade-off between failure-free conditions and controller failures are …

… In this paper, we propose a controller placement strategy that plans ahead for controller
failures to avoid … in case of link and node failures as a metric to locate the controller. A …

… Thus, if controller C1 fails, the network is managed by controller C2. We find that upon fail…
Their greedy heuristic places the controller at the node with the maximum number of protected …
