Call admission control (CAC) of time-dependent video connections is an important issue for network traffic engineering. The impact of this traffic dependence on video call acceptance region is examined in this article. We considered two different CAC mechanisms; (1) a descriptor- based CAC mechanism and (2) a measurement-based CAC (MBCAC) mechanism. The proposed MBCAC is a hybrid measurement scheme that includes a Kalman filter and a real-time Hurst estimation. We investigated several buffer sizes and video sequences with different dependence degrees. For the accuracy of the Hurst estimation, we developed a Hurst parameter package. The package consists of three different estimators, R/S, Higuchi and Abry-Veitch (wavelet). An important result shows that long-range dependence and short- range dependence connections have similar admission regions.
