A new dynamic bandwidth allocation scheme for ATM networks

An 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. The average virtual cell loss probability (VCLP) is employed to measure the quality of service. This novel approach can minimize VCLP of the system by optimizing Q and utilize the link capacity efficiently and provide high throughput in multi-class traffic environment.
