MPLS performance modeling using traffic engineering to improve QoS routing on IP networks

The Internet architecture has evolved over time, incorporating new technologies and adapting to the changing needs of its users. The introduction of multi-protocol label switching (MPLS) as a part of the Internet forwarding architecture has immediate applications in traffic engineering (TE) and quality of service routing (QoSR). MPLS supports throughput and delay sensitive real-time media services such as Internet-based distance learning or I-DL. This paper presents a performance service model, which incorporates TE and QoSR of the MPLS to support I-DL while retaining the efficiencies of the backbone structure of the Internet. This new service model is simulated using OPNET and its performance is compared to existing IP routing algorithms.
