QoS routing is crucial in supporting network-based multimedia applications. In this paper, we identify the resource over-committing issue that exists in many proposed QOS routing algorithms. Over-committing network resource increases the possibility of blocking future requests. A novel QOS routing algorithm called friendliest routing algorithm is proposed to tackle this issue. In terms of blocking ratio, our evaluation shows that the proposed algorithm achieves 10% improvement in general and 30% in some circumstances.
