Abstract

In this study, a queue tuning algorithm (QTA) supporting QoS for traffic engineering in Multi-Protocol Label Switching (MPLS) networks is introduced. The algorithm aims at mapping different traffics, consisting of both Best-Effort traffic and traffic with QoS requirement, onto different queues while preserving the order of packets within a flow in traffic. The algorithm supports QoS while realizing load balancing to optimize network resource utilization. Simulation indicates that the algorithm works well in MPLS networks.
