The Software Defined Network (SDN) is a relatively new paradigm that aims to tackle the lack of centralization in the existing network by separating the control centre from the programming data plane. The controller keeps an overview of the structure of the whole network, which makes it vulnerable to possible topology poisoning attacks. Topology...

Software-Defined Networks (SDNs) are a promising new network design paradigm that allows for better control of the network. But as with any new software implementation, there are new security concerns that arise. In the past there have been various papers covering specific side-channel attacks on SDNs; most of them consist of either using time...

Software-Defined Networking (SDN) is a relatively new networking paradigm that proposes to separate the control and the data logic in networks. The control logic is centralized in a controller, which allows for a programmable network. SDN is promising but also intro- duces some critical security vulnerabilities to networks. This work proposes a...

Software Defined Networking (SDN) is a new paradigm that allows for greater reliability and more efficient management compared to traditional networks. However, SDN security is a developing field, and research towards fixing significant security vulnerabilities is still ongoing. One major threat to SDN security are attacks that seek to exploit...

Nowadays, the number of Distributed Denial of Service (DDoS) attacks is growing rapidly. The aim of these type of attacks is to make the prominent and critical services unavailable for legitimate users. HTTP flooding is one of the most common DDoS attacks and because of its implementation in application layer, it is difficult to detect and...

In recent years, the explosive growth of the Internet has led to an increment in the number of Distributed Denial of Service (DDoS) attacks. HTTP Flooding is a critical DDoS attack that targets HTTP servers to prohibit users from receiving HTTP services. Moreover, it saturates the link bandwidth and consumes network resources. Because the...

Large data centers are currently the mainstream infrastructures for big data processing. As one of the most fundamental tasks in these environments, the efficient execution of distributed data operators (e.g., join and aggregation) are still challenging current data systems, and one of the key performance issues is network communication time....

The emergence of Multi-Access Edge Computing (MEC) technology aims to extend cloud computing capabilities to the edge of the wireless access networks, i.e., closer to the end-users. Thus, MEC-enabled 5G wireless systems are envisaged to offer real-time, low-latency, and high-bandwidth access to the radio network resources. Thus, MEC allows...

In-vehicle communication systems are usually managed by controller area networks (CAN). By broadcasting packets to their bus, the CAN facilitates the interaction between Electronic Control Units (ECU) that coordinate, monitor and control internal vehicle components. With no authentication mechanism for identifying the legitimacy and source of...

Software-defined networking (SDN) is a cornerstone of next-generation networks and has already led to numerous advantages for data-center networks and wide-area networks. However, SDN is not widely adopted in constrained networks, such as Wireless Sensor Networks (WSN), due to excessive control overhead, lossy medium, and in-band control...

Software-Defined Networking (SDN) potentially can improve the flexibility and management of Wireless Sensor Networks (WSNs). To investigate the impact of SDN on WSN, in this thesis, we consider three Software-Defined Wireless Sensor Network (SD-WSN) frameworks, namely SDN-WISE, SDWN-ONOS, and TinySDN. After comparing these frameworks, the...

SDN improves network flexibility which is constrained by network protocol in a conventional network by decoupling the control plane and the data plane of the network. This is the reason why many companies and universities migrate their network to SDN, there will be more SDN network in the future. Yet SDN network mainly depends on the controller...

Our research is exploring how the computer network technology of Software-Defined Networking (SDN) can benefit an IT service provider. SDN is a novel technology that is capable of managing a whole network based on a single centralized entity. As a result an SDN enabled network becomes more flexible, automatable and programmable to satisfy users’...
