A new dynamic bandwidth allocation scheme for ATM networks

The asynchronous transfer mode (ATM) is widely recognized as the most promising technology for developing the broadband ISDN. A new dynamic bandwidth allocation scheme called minimum overflow traffic algorithm (MOTA) is proposed to assign the bandwidth b/sub i/ for each traffic class in the hierarchical admission control structure. An overflow traffic function Q is used to adjust the bandwidth assignment each time when a new connection is required. This algorithm sets the mean overflow traffic to bandwidth ratio in the system as the optimization object function Q and adjusts the bandwidth assignment to each traffic class by optimizing Q.
