The existing Active Queue Management (AQM) algorithms, including the fairness-aimed ones, are notably vulnerable to spoofing DDoS attacks. We propose a Resilient Stochastic Fair Blue (RSFB) algorithm against spoofing DDoS attacks. The basic idea behind RSFB is to record the responsive normal TCP flows and rescue their dropped packets. Simulations and analysis show that the RSFB algorithm is highly...
This study is focus on SIP of VoIP, and simulated and analysed by NS2. In addition, because of the security issues are the main factor to affect its popularization, and the DDOS attack has become one of the more serious issues in VoIP network security domain. Therefore this research carries on the simulation analysis to various types attack by NS2, and further discusses under the DDoS attack between...
Differentiated Services (DiffServ) networks categorize routers into edge routers and core routers. In core routers, one of the technological challenges is how to implement differentiated bandwidth allocation and TCP protection together with low complexity. We present an Active Queue Management (AQM) scheme called CHOKeW. A method is borrowed from a previous scheme, CHOKe, which draws a packet at random...
Convenient, rapid, efficient and anonymous characteristic of P2P technology, enables P2P network gathering enormous users very quickly, and P2P traffic has occupied 60~80% bandwidth of Internet. Such giant traffic has formed a threat to the service quality of other Internet application and the security of Internet itself. However, most study about P2P traffic focuses on traffic monitoring and characteristic...

A simple and yet effective denial of service (DoS) attack on voice over IP (VoIP) proxies that based on session initiation protocol (SIP), is to flood the server with requests that their addresses do not exist and are irresolvable. Different security schemes and possible attacks have studied from the qualitative view on the most of network security researches and these researches are less considered...
