The implementation of the premium services for MPLS IP VPNs

Abstract

Multiprotocol label switching (MPLS) is a method of switching IP packets through a network by applying simple labels to packets. It provides the privacy and quality of service (QoS) advantages of connection-oriented services. Other benefits of MPLS include traffic engineering capabilities needed for the efficient use of network resources. Traffic engineering shifts the traffic load from overutilized portions of the network to underutilized portions, according to traffic destination, traffic type, traffic load, time of day, and so on. As the MPLS IP VPN market grows, QoS offerings is required to provide VPN groups premium services as well as to differentiate in existing VPN groups. Faced with this challenge, MPLS IP VPNs need to offer both best effort and premium services that ensure traffic engineered path label switched path (LSP) for satisfy a variety of QoS requirements. In this paper, we focus on the issues related to QoS provision for MPLS IP VPN services. We propose the workflow of MPLS IP VPN application to provide best effort and premium services. We discuss the design to arrive at the architecture of the MPLS IP VPN module to support best effort and premium services. This can provide way how to realize MPLS IP VPN services in a router on the analysis of requirement. In conjunction with MPLS, the implementation of MPLS IP VPNs provides label distribution to setup traffic engineered LSP on a PE router
