Abstract
Through deeply analyzing on the principle, mode, character of DoS, and the DoS attack faced by SIP network, combining with the idea of Client Puzzle, DFA, long-distance linkage, host linkagethe, the character of SIP network, and the principle of SIP proxy server, the defence model of SIP proxy server for DoS attack was put forward, and the testbed to test the ability of this model to resist DoS attack was designed. The experiment result proves that this model can effectively resist the DoS attack for SIP proxy server with millisecond delay of signal transfer, and improves the usablity of SIP network.
