In Software-Defined Networking (SDN), the data plane is defined by the switches which are connected to a set of controllers defining the control plane. The intercontroller connections have lacked the same focus in the literature as the switch-controller connections, despite the set of logically centralized controllers being the brain of the SDN network. In this paper, we address a bi-objective joint optimization problem involving the controller placement problem, geodiversity and intercontroller availability guarantees. The availability guarantees imply a subgraph whose links can be upgraded at a given cost. The geodiversity constraints extend robustness to disasterbased failures. To solve this NP-complete non-linear problem, we employ a heuristic strategy based on the decomposition into manageable subproblems.

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.

“…This decreases the load on the controller for handling large flow requests. Architecture of the controller to protect the SDN from problems has been analysed in [43]. To limit the network applications access to the controller system and the managed network, a system of fine grained permission has been investigated for applications in [44].…”

In the present days, network technologies have always been an important part of success in any communication system. The internet has led to a digital society formation, where from anywhere almost everything is linked and is easily reached. Despite their widespread adoption, traditional IP networks are intricate and very hard to manage. According to predefined policies, it is hard to both configure and reconfigure the network in the case of response to faults, loads and changes. This can lead to problems in effectiveness due to the slow scalable IT infrastructure growth. In this paper, an extensive review on Software Defined Networking (SDN) is presented. Response to problems by providing novel functions to the entire network topology can be easily carried out with SDN. With software defined networking, administrators have the opportunity to abstract the underlying infrastructure of the network for applications and services. After introducing SDN, key concepts and its traditional networking differences, its roots and the activities of standardization are explained in an attempt to expect the future growth of this new model and discuss the main on-going research attempts and challenges. We formulate a scenario classification in which these technologies may contact and observe a significant degradation in the web services performances, in terms of response time and availability. At last we analyse the SDN position as the main enabler of a software-defined environment. SDN present novel networking ideals, simplifying management of network and facilitating evolution in network.
