FlowSM: Flow Scheduling Mechanism in Coordinated Mitigation of Large-Scale DDoS Attacks

We propose to construct mitigation of large scale of DDoS attacks based on “Weight Deficit” flow scheduling mechanism to improve the network maximize throughput and minimize the network congestion for mitigating DDoS attacks. Thus, the path of higher available bandwidth is mitigated of large-scale DDoS attacks. This flow scheduling mechanism able to maximize network throughput and to minimize the congestion with among elephant flows, mice flows, round robin flows. Flow Scheduling Mechanism (FlowSM) which is more adaptive to available bandwidth links and mitigate the congestion flows of the network and also mitigate the large scale of DDoS attacks. Weight deficit flow would to find the highest capacity of nodes in a network and assign weight ratio of those nodes. So it would able to provides a stable flow scheduling mechanism scheme which is adaptive to the available bandwidth links and mitigate large scale of DDoS attacks. Experiment results show that maximize network throughput of flow scheduling mechanism improves to mitigate the large scale of DDoS attacks. Simulation-based results shows that our technique effectively more defensive a victim server against various DDoS attacks. In this research paper, we propose a distribute approach to defend against DDoS attacks by coordinating flow scheduling mechanism across into the network.
