摘要： A method for implementing DS-TE in MPLS network is disclosed. The method includes carrying Quality of Service (QoS) parameters relating to resource allocation in a path message when establishing an LSP; reserving bandwidth resource for service traffic according to the QoS parameters; using the reserved bandwidth to forward service traffic after the LSP is established. A system for implementing DE-TE in the MPLS network is also disclosed. The system includes an Ingress LSR, a relay LSR and a Egress LSR. The Ingress LSR or the relay LSR carry QoS parameters relating to the resource allocation in the path message for establishing LSR.

An LSR is further disclosed according to the present invention. According to the method, system and LSR of the present invention, bandwidth resources can be allocated based on different service class and thus granularity for the DiffServ traffic engineering is further refined.
