A New Dynamic Self-adaptive Diffluence Algorithm for VoIP Gateway of Intelligrid

Aiming to cope with various attack problems that the VoIP (Voice over Internet Protocol) network of Intelligrid is confronting, This paper designs an active VoIP security defense model, Based on the model, a dynamic self-adaptive diffluence algorithm that can be applied to the VoIP Gateway was proposed. It combines advantages of UBS selection strategy and weighted Bayesian classification algorithm, the algorithm can accurately, quickly complete the task of intrusion detection through using few high-quality training sample for learning. Experimental results demonstrate the algorithm is more accurate under the smaller training set.
