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
