Data Communications over ATM using SVCC: A Survey of Issues, Problems and Solutions

Connections in an ATM network are made using virtual channel connections which can be either permanent (PVCC) or switched (SVCC). SVCC requires a signalling protocol which is being standardised by international standards organisations. Because of the cost eeectiveness of SVCCs over PVCCs for data communication in an ATM environment, a signii-cant amount of work has been carried out to determine the most cost-eecient and eeective ways to operate SVCCs. These include issues such as holding time policies, pricing schemes, eeect of call blocking, etc. The aim of this paper is to survey the work done in the area of SVC with special emphasis to the above mentioned issues.
