Traffic specification plays a crucial role in the resource reservation for video services over the packet-switching networks. The current development of QoS-guaranteed service still leaves a wide space for the selection of traffic specification. We propose a new method to estimate the traffic specification of variable-bit-rate (VBR) video for deterministic service. The method is based on the concept of empirical envelope and the delay bound. The solution shows to be simple yet it provides excellent network utilization. As opposed to stochastic models, a number of methods have been proposed based on the deterministic traffic model [2][3][4], which was initiated by Cruz [6]. The traffic specification is estimated as an approximation of the so-called empirical envelope, resulting in a worst-case characterization of the video traffic. The services developed in this track are often called deterministic services. In practice, the guaranteed services of ATM and IETF belong to this category. The traffic specification can be determined further by various extensions such as the trial and error approach [8], the method based on some constraints of σ and ρ [12], the method based on deterministic model but also exploiting the periodic pattern of video frame sizes for statistical multiplexing [4][5] etc.
