“…The similar researches also include K-Critical [19]. Simulated annealing is adopted in [20] to increase the reliability of SDN by placing appropriate controllers in the network. Different from the research which improves the resilience of the southbound connections, an approach is proposed in [21] to endure controller failures in SDN-enabled wide area networks.…”

Abstract-One grand challenge in Software Defined Networking (SDN) is to select appropriate locations for controllers to shorten the latency between controllers and switches in wide area networks. In the literature, the majority of approaches are focused on the reduction of packet propagation latency, but propagation latency is only one of the contributors of the overall latency between controllers and their associated switches. In this paper, we explore and investigate more possible contributors of the latency, including the end-to-end latency and the queuing latency of controllers. In order to decrease the end-to-end latency, the concept of network partition is introduced and a Clustering-based Network Partition Algorithm (CNPA) is then proposed to partition the network. The CNPA can guarantee that each partition is able to shorten the maximum end-to-end latency between controllers and switches. To further decrease the queuing latency of controllers, appropriate multiple controllers are then placed in the subnetworks. Extensive simulations are conducted under two real network topologies from the Internet Topology Zoo. The results verify that the proposed algorithm can remarkably reduce the maximum latency between controllers and their associated switches.

Abstract-Resilience against disaster scenarios is essential to network operators, not only because of the potential economic impact of a disaster but also because communication networks form the basis of crisis management. COST RECODIS aims at studying measures, rules, techniques and prediction mechanisms for different disaster scenarios. This paper gives an overview of different solutions in the context of technology-related disasters. After a general overview, the paper focuses on resilient Software Defined Networks.

Abstract-In this paper we take a closer look at the operation of software defined networking (SDN) in intra-domain networks. The focus is on the dependability issues related to interworking of SDN controllers, network OS (NOS), and forwarding in the data plane. Both the separation of the control and data planes, and the (virtually) centralized control processes, are challenging from a dependability perspective. In particular, consistency in operation and information is a challenge, both between the control and data planes, but also within a given plane. To ensure the necessary level of consistency there could be a conflict with the strict realtime requirements given by the per-flow operation of the SDN controller. A principle system model is introduced to discuss the consistency challenge, and to point out undesirable cyclic dependencies between functions that are necessary to configure and operate SDN. The separation of control processing and forwarding do also introduce structural vulnerabilities, which are exemplified.
