SIP (Session Initial Protocol) is attacked easily by DoS flooding thanks to it's open, the queue scheduling scheme can alleviate the SIP server's influence caused by DoS flooding attack at a certain extent. By analyzing SIP message character and existing queue scheduling scheme, we propose a INVITE DoS flooding attack defense mechanism based on CWFQ (Custom Weighted Fair Queue) and simulates it's performance. The result of simulation proves that the scheme is proposed in this paper is more effective than FIFO queue and PQ (priority queue) in defense of INVITE flooding attack.
