Simulation of DDoS attack on software defined networks

Software defined network technology is attractive in the modern world. In the networking community, very few have escaped its impact. This is a new approach to building the architecture of computer networks. The network management layer and data transfer layer are separated, and network management functions are transferred from routers and switches to software applications running on a separate controller server. The article provides an overview of the most common attacks on software defined networks, their classification and the goals that attackers want to achieve. As software defined network devices and systems enter the market, security in software defined network must be brought up on the agenda. This paper provides a comprehensive overview of the security studies in software-defined networks that have been conducted to date. Both the security improvements that will result from using the software defined network platform and the security issues associated with the platform are discussed. By categorizing existing works, a set of conclusions and proposals for future research directions is presented. What is more, a study was conducted on the impact of DDoS attacks on the software defined network. Appropriate conclusions are drawn from the results obtained after modeling attacks using Mininet technology.Software defined network technology is attractive in the modern world.
