Monitoring the Quality of Service on an ATM Network Carrying MMB Traffic Using Weighted Significance Data

Abstract

Recent years have shown a great change in the telecommunication environment. Thus far, separated voice and data networks are being replaced by heterogeneous networks capable of supporting a diverse variety of traffic. Quality of Service (QoS) has become an important factor in the deployment of the next-generation of data networks. The continuing increase in the volumes of data to be carried by ATM networks has boosted the need to administrate the QoS. Although the Connection Admission Control (CAC) algorithm is not specified by the ITU-T, it is still widely used to moderate bandwidth allocation and User Parameter Control (UPC) algorithms can ensure that contractual stipulations are met. However, if an accurate QoS monitoring technique is implemented, both the CAC and UPC mechanisms will have a firmer foundation upon which to base their decisions. This will mean a firmer control on the bandwidth allocation. This paper focuses on the use of data interpretation to monitor the QoS of source bursty traffic based upon delay.
