Abstract A novel distributed QoS routing algorithm, the metric of which is bandwidth, is presented in this paper. It not only keeps the merits of simplicity and low link overhead in traditional distributed QoS routing algorithm, but also can reduce resource fragments and admit more services into a network with heavy load. The high performance of this algorithm accompanies some delay during path setup. But the performance remains with great reduction in this delay when the start threshold of this algorithm is considered. The extensive simulation results also indicate its correctness and efficiency.
