In the recent ten years, with the development of new applications through Internet such as multimedia or net-worked control applications, users need more and more qual-ity of service (QoS). However, the requested QoS is not the same depending on the application. Most of the new mod-els to manage internet traffic are based on specific QoS cri-teria which should be optimized. This paper presents main multiprotocol label switching (MPLS) approaches such as MPLS adaptive traffic engineering (MATE), load distribu-tion in MPLS (LDM) and load balancing over widest disjoints paths (LBWDP) that are new models for traffic engineering. It also introduces periodic multi-step (PEMS) algorithm that adapts the offered quality depending on the class of the routed traffic. Keywords-- differentiated service, multipath routing, QoS rout-ing, quality of service, traffic engineering.
