摘　　要：Current network for real-time service de- livery needs to maintain end-to-end service quality under various network uncertainties, e.g. traffic demand fluctua- tions or topological changes. This paper investigates coor- dinating AQM-RED and OSPF-TE for guaranteeing SLA under such network dynamics. The simulation experiments show that the proposed approach can significantly reduces the detrimental impact of link failures and traffic demand variation on end-to-end QoS provisioning without intro- ducing additional complexity or overheads to the current network paradigm.
