The paper presents a novel approach for a Call Admission Control scheme which employs the Hurst parameter as an index of burstiness suitable to characterize the self similar nature of multimedia traffic. It assumes also the knowledge of the mean and the variance of the process. These parameters can be obtained with an off-line statistical analysis of the traces (in the case of distribution services such as Video on Demand) or by real-time suitable estimators (in the case of interactive services such as videoconference). The analysis of the multiplexing gain obtained considering a fair distribution of the bandwidth between homogeneous and heterogeneous sources (with respect to their Hurst parameters) is presented. The results are compared to peak allocation schemes currently adopted over wide area ATM networks.

Abstract
The paper presents a novel approach for a Call Admission Control scheme which employs the Hurst parameter as an index of burstiness suitable to characterize the self similar nature of multimedia traffic. It assumes also the knowledge of the mean and the variance of the process. These parameters can be obtained with an off-line statistical analysis of the traces (in the case of distribution services such as Video on Demand) or by real-time suitable estimators (in the case of interactive services such as videoconference). The analysis of the multiplexing gain obtained considering a fair distribution of the bandwidth between homogeneous and heterogeneous sources (with respect to their Hurst parameters) is presented. The results are compared to peak allocation schemes currently adopted over wide area ATM networks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
