Due to the traditional overlay network QOS routing algorithm fails to consider the effects of the resource bottleneck on the routing selection, it results in the local congestion of the system. Therefore, this paper proposes a Fair Load-Balancing QOS overlay Routing F-LBQAR algorithm. The algorithm introduces the resource fairness index, sets up a new load-balancing utility function, and adopts the adaptive weighted method in the system's load state to correct the weight restriction of QOS. The experimental results show that the algorithm in this paper can reduce the probability of network congestion caused by resources bottleneck and improve the QOS service success rate and the throughput of the system.
