title = "Latency-aware reliable controller placements in SDNs",
abstract = "Most existing research on controller placement in Software-Defined Networking (SDN) investigated controller placements without jointly taking into account both the communication reliability and the communication latency between controllers and switches if any link in the network fails. In this paper, we first introduce a new latency metric that considers the communication delay between the switches and the controllers with and without the single-link-failure. We then formulate a novel SDN controller placement problem with the aim to minimize the communication delay, for which we propose an efficient algorithm. We also show that there is a non-trivial trade-off between a primary path and its backup path in terms of communication delay. We finally conduct experiments through simulations. Experimental results demonstrate that the proposed algorithm is very promising.",
