The motivation for characterization of VoIP traffic is that VoIP quality is mainly affected by some impairments in transport network in terms of delay, jitter and packet loss. It is shown at the paper that the prediction of transport network resource to satisfy the VoIP QoS is important to find an perceptual optimization of playout buffer, and is able to provide effecient way to compute resource consumption in VoIP transport network. This paper shows two models to caharcterize VoIP traffic in transport network, and proposes the novel mechanism to compute an amount of resource consumption. The mechanism evaluates its availability of VoIP call arrived newly in order to sustain a stable VoIP quality level. The applicability of the proposed mechanism in the paper will be stressed in terms of computational efficiency of dynamic real time computation algorithm.
