Abstract [eng] Nowadays there are lot of ways how to detect various types of DDoS attacks, but in order to stop, or at least to mitigate the impact of such DDoS attacks not enough work is done. It is very difficult to choose the right DDoS mitigation method. The research of DDoS attacks mitigation can provide a good manual how to choose the most appropriate method. „BGP DDoS Diversion“ method is one of the most effective and least cost to deliver DDoS mitigation method. This method is implemented using BGP protocol. BGP diversion mechanism is used to announce a specific part of the provider‘s network to (a part of) the Internet. Announcing a specific part of this network will divert the DDoS traffic and thereby prevent other parts of the provider‘s network becoming unreachable. This gives the provider the ability to continue providing services of the rest of his custumers. This research was based on analyzing the DDoS mitigation methods. For the better analyzes the „BGP DDoS Diversion“ method was chosen. To analyze this method the virtual environment was the best way to accomplish this task. OPNET modeler software was chosen to create the virtual environment. Using OPNET the virtual network was created. Virtual network was based on Internet network standards. „BGP DDoS Diversion“ method was implemented and tested in the virtual network. This research provides the detail analyzes of „BGP DDoS Diversion“ method.
