Abstract

In this paper, a simplified QoS scheme is proposed. The proposed scheme uses a Virtual Link which is a Label Switched Path (LSP) set connected from Ingress Label Egde router (LER) to Egress LER. LSPs of the virtual link must be managed dynamically according to network status. The traffic in the virtual link is distributed among LSPs to reduce service unbalancing by the flow. In this proposed model, Per-Hop-Behavior (PHB) is implemented in each LSP of ingress LER and Core LSRs just guarantee bandwidth. These features make it simple and easy to provide Quality of Service in MPLS network. The characteristics of the proposed scheme and the ffiTF scheme are compared logically and analyzed through simulations.
