QoS Sensitive Routing in DiffServ MPLS-TP Networks

摘要：

QoS sensitive routing is a very important component of traffic engineering in DiffServ MPLS-TP networks. This study investigated the characteristics of packet scheduling algorithms and the problem of unfairness when QoS routing does not consider the mix of traffic classes. A new routing scheme STE-QOSPF-Mix, which takes the reserved bandwidth supported WFQ algorithm into account, is proposed. To determine the QoS route for a flow request, STE-QOSPF-Mix considers the effective available bandwidth instead of residual bandwidth of the path, which is more suitable in DiffServ MPLS-TP networks. The simulation results show that our proposed STE-QOSPF-Mix scheme outperforms the TE-QOSPF-Mix scheme in terms of packet loss ratio and end to end delay.
