ABSTRACT
This article discusses various issues related to multi-protocol label switching (MPLS), user to network interface (UNI), and end-to-end quality of service (QOS) in relation to Internet service. MPLS has evolved away from its original purpose of improving router performance, to its current role of optimizing and enhancing carrier backbones. Existing MPLS specifications already allow service providers (SPs) to meet two necessary conditions for QOS: guaranteeing the bandwidth of label switched paths (LSPs) and providing differentiated processing of packets associated with LSPs. However, additional capabilities are needed so that QOS can be applied end-to-end across multiple networks and network domains. Access links are frequently to blame when users perceive inadequate QOS. The primary bench to the enterprise of the proposed MPLS UNI is that it will unify and simplify end-to-end QOS. The main feature of the MPLS UNI is an MPLS LSP between the customer edge device (CE) and the provider edge device. The MPLS UNI LSP connection capability is an LSP-based approach for creating easily configurable CE-to-CE paths, with the sending CE taking charge of the admission.
