Research on Low-Rate Denial-of-Service Attacks against XCP

Abstract

LDoS attacks are a new type of denial of service attacks put forward by Kuzmanovic. According to several experiments, it is very effective in degrading the normal TCP senders throughput. XCP is a feedback-based congestion control protocol; it supplies feedback which is acquired through the use of a congestion header on each sent packet from the network to the sender on the maximum rate for injecting data into the network. In this paper, we studied the TCP protocol with explicit congestion control and found it has some characteristic in defending LDoS attacks, which give us a new idea to prevent LDoS attacks.
