Future communications networks are expected to support applications with quality of service (QOS) requirements. Supporting QoS poses major challenges due to the large size and complex structure of networks. Several studies have addressed different aspects of QoS routing. In this paper, we present a new approach of QoS routing based on the concept of multiple routing tables. Traffic with QoS requirements will have their own routing table. This scheme can prevent such traffic from concentrating on some link, so it can improve their performances. From our extensive simulation results, we have found that both packet loss of QoS traffic and throughput of best-effort traffic can be improved by using our scheme.
