Simulation of DDOS Attacks on P2P Networks

Internet was designed for network services without any intention for secure communication. Exponential growth of internet and its users have developed an era of global competition and rivalry. Denial of service attack by multiple nodes is capable of disturbing the services of rival servers. The attack can be for multiple reasons e. g. extortion or to beat the rivals. Peer to peer and cloud computing offer content services and content delivery networks and require reliable communication medium and servers for the clients. IBM, Amazon and Microsoft are offering peer to peer, cloud computing using port to port addressing and priority level identification and filtering mechanism by embedded Java and XML technologies. Cloud computing also involves various other technologies however analysis of every aspect of clouding is beyond scope of this paper. Oversim, OMNET, OPNET, ns2/ns3, GlomoSIM, Cisco packet tracer etc. are test bed simulation tools to analyze and generate reliable data. We have used Gia network within Oversim simulator to simulate a virtual overlay network DDoS attack based on work conducted by Srivatsa et. al. [9] and Naoumov et. al. [8].
