Detection and Mitigation of Distributed Denial-of-Service (DDoS) Attacks on Software Defined Networking (SDN)
The evolution of information and communication technologies has brought new challenges in managing the Internet. Software-Defined Networking (SDN) aims to provide easily configured and remotely controlled networks based on centralized control. Since SDN will be the next disruption in networking, SDN security has become a hot research topic because of its importance in communication systems. A centralized controller can become a focal point of attack, thus preventing the attack on the controller will be a priority. The whole network will be affected if the attacker gains access to the controller. One of the attacks that affect SDN controller is DDoS attacks. The aim of this project is to explore and evaluate one of the common detection and mitigation techniques. Later, further ideas on how to improve the performance of SDN during such attacks are investigated.

Performance Analysis and Comparison of TCP Congestion Control Algorithms
Current video streaming applications have gained the interest of various industries due to their ability to create a comprehensive reality and get people close to each other. Constraints on available resources (such as bandwidth) cause packet loss and re-transmission when the network is overloaded, which refers to “congestion”. The main concept that controls the conversational video for WebRTC is the congestion control algorithm. The goal of this project is to provide an analysis of the performance of different TCP congestion control algorithms. Furthermore, a suitable environment is implemented to achieve the optimum performance for the selected algorithms.

Performance Evaluation and Analysis of Software-Defined Network (SDN) Under Various Traffic Types
Software Defined Networking (SDN) is a new networking paradigm proposed to change the perspective of Networking. Although SDN brought several advantages over traditional Networking, it has several issues related to its centralized controller, especially during high traffic load, which can cause high networking latency or eventually lead to network collapse. Thus, performing an analysis specifically addressing this issue is crucial and exciting. The main goal of this work is to analyze the performance of Software Defined Networks under certain traffic types and loads. Furthermore, clear guidelines are required after analyzing the obtained results to ensure network stability and possible security solutions. Multiple scenarios will be implemented, such as using one server with one host as the initial phase to measure the actual throughput and latency. Furthermore, the number of hosts increases as we move forward to analyze the performance of the SDN network at each phase.
