Autonomous networking research to applies intelligent agent and multiagent systems theory to network controlling mechanisms. Deploying such autonomous and rational entities in the network can improve its behavior in the presence of very dynamic and complex control scenarios. Unfortunately, building agent-based mechanisms for networks is not an easy task. The main difficulty is to create concise...

Software-defined networking (SDN) provides fine-grained network control and monitoring that simplifies network management. Unfortunately, upgrading existing enterprise networks, comprised of numerous “legacy” switches, to SDN is often cost-prohibitive. We argue that it is possible to achieve most of the benefits of a fully deployed SDN at a fraction of the cost by strategically replacing only f...

Mininet is network emulation software that allows launching a virtual network with switches, hosts and an SDN controller all with a single command on a single Linux kernel. It is a great way to start learning about SDN and Open-Flow as well as test SDN controller and SDN applications. Mininet can be used to deploy large networks on a single computer or virtual machine provided with limited reso...

The internet of things (IoT) and wireless sensor networks (WSNs) are two promising technologies for supporting new services applications. However, because IoT WSN entail interaction transaction device topology discovery protocols, facing some challenges. Topology (TD) is important in since nodes (SNs) the main points this network. Networking these SN (IoT-devices) has a few difficulties such as...

Software-defined networking (SDN) promises to improve the programmability and flexibility of networks, but it may bring also new challenges that need to be explored. One open issue is the quantitative assessment of the properties of SDN backbone networks to determine whether they can provide similar availability to the traditional IP backbone networks. To achieve this goal, a two-level availabi...

Software-Defined Networking (SDN) has significantly enriched network functionalities by decoupling programmable network controllers from the network hardware. Because SDN controllers are serving as the brain of the entire network, their security and reliability are of extreme importance. For the first time in the literature, we introduce a novel attack against SDN networks that can cause seriou...

Software-Defined Networking (SDN) is an emerging topic and securing its data and control plane is of great importance. The main goal of malicious SDN applications would be to compromise the SDN controller which is responsible for managing the SDN-based network. In this paper, we discuss two existent mechanisms aiming at protecting aforementioned planes: (i) sandboxing of SDN applications and (i...

Software-defined networking (SDN) enables the flexible and dynamic configuration of a network, and OpenFlow is one practical SDN implementation. Although it has been widely deployed in actual environments, it can cause fatal flows. In this paper, we consolidate the security threats to OpenFlow mentioned in previous work and introduce a new security checksheet that includes risk assessment metho...

Distributed software-defined networks (SDN), consisting of multiple inter-connected network domains, each managed by one SDN controller, is an emerging networking architecture that offers balanced centralized control and distributed operations. Under such networking paradigm, most existing works focus on designing sophisticated controller-synchronization strategies to improve joint controller-d...
