AB  - Distributed Denial of Service (DDoS) describes the unavailability of service provided by the server in the network to its valuable clients in the network. Many researchers focus on the problems in network resources availability and its allocation to the clients without any time delay and in an efficient manner. The main task in the process includes the attack detection process which helps to identify the deviation of packet flow from the normal traffic. In this study, the detection of the DDoS attack is carried out with the help of the network capacity (called as router capacity) in processing and forwarding of the information packets. The packet flow is analyzed with the help of Z-test to check whether there is an abnormal traffic occurred in the network by focusing on the data arrival rate at different time intervals. Based on the result, the information packets are analyzed and check with the threshold value for forwarding processing by the router.
