One of the most damaging and widely used cyber-attacks is the Distributed Denial of Service (DDoS) attack. A large amount of attack traffic generates traffic congestion and disables online services by disrupting ISP services. DDoS attacks are extremely difficult to detect and mitigate. DDoS attacks are launched using a variety of strategies and approaches, including IP spoofing, botnets and tools. Traditionally hardware, i.e. middle boxes such as Routers, firewall, load balancer and IDS are used to reduce the traffic volume of the DDoS attack. But with the origination of the Network Function Virtualization researchers started to propose various techniques for the mitigation of the volume of the DDoS attack. In this paper, we have reviewed various proposed techniques to defeat DDoS attacks and their efficiency in reducing the attack.
