In order to improve the quality of VoIP services, an adaptive routing method is proposed in the application layer of Internet gateways. This method determines routing paths based on the average one-way delays in a predetermined re-routing interval. In order to evaluate the performance of the method, five different routing policies are specifically designed and tested. Experimental results show that the method can improve the QoS of Internet phone services.
