Bandwidth Management and Call Admission Control (CAC) Methods in Asynchronous Transfer Mode (ATM) Switching Systems

摘要

The present invention relates to bandwidth management and call admission control using overload factors for bandwidth management and call admission control (CAC) methods in asynchronous transmission mode (ATM) In order to provide a call admission control method according to an efficient management method for calculating an appropriate amount of bandwidth, when the operation state of an asynchronous transfer mode (ATM) exchanger is normal, the link utilization is maximized. In an overload situation, Or eliminates the overload situation.
