Abstract
MPLS is an extension of the Internet network layer that offers, besides the legacy connectionless service, a service based on virtual connections. The concept of LSP (Label Switched Path) allows the introduction in the network layer of virtual connection while offering a great flexibility of aggregation, an essential property to allow the continuous growth of the traffic. By offering new routing fonctionnalities, MPLS contributes to efficient traffic engineering needed by the traffic evolution and the limitations of the classical routing.

MPLS is not the only possible extension of the classical IP architecture. IP QoS based on DiffServ allows the introduction of a differentiation of the services that is needed to support the integration of all the applications on the Internet not anymore dedicated to elastic applications. IP QoS is an essential part of the new architecture of the Internet. MPLS and IP QoS may be deployed alone but they gain to be deployed together. The evolution of the Internet classical architecture to MPLS on one side, to IP QoS on the other side and finally to the combination of both is the subject of this tutorial. It aims at all those who are concerned by the evolution of the network architectures and by the evolution of the services.

Instructor
Andre DANTHINE, Professor at the University of Liège since 1967, created a Research Unit in Networking (RUN) in 1972, decided to direct his research to the problems related to computer networks and established links with researchers of ARPANET and CYCLADES networks. He focused his works to the network architecture and the protocol theory. His group conducted research and developement projects with the Société Générale de Banque, EDF-GDF and Bell Telephone In 1983, Professor Danthine launched the ESPRIT I Project 73 aimed at the development of a high speed network for the interconnection of heterogeneous LANs on a broad site. This Project concluded, in 1989, with the installation, on the Campus of the University of Liege, of the BWN (Backbone Wideband Network) prototype (more than 18 km of optical fiber with a data rate of 140 Mbps). Professor Danthine has been also involved in the ESPRIT, RACE and ACTS Projects. Since its creation in 1992, he has been the chairman of the COST Action 237 on "Multimedia Telecommunication Services". Professor Danthine is a member of ACM and IEEE; he is the editor of several books and proceedings and the author of more than a hundred papers. Chairman of the TC6 of IFIP from 1979 to 1985, he has been Governor of ICCC since 1982. CRB Fellow in 1960, he received the Melchior Salier Prize in 1961, the "Bell Telephone-100th Anniversary" prize in 1983 and the IFIP Silver Core in 1986. In 1993-1994, he was Francqui Professor at the VUB. He is Doctor of Science Honoris Causa of the University of Kent (1991), and of the University Paul Sabatier in Toulouse (1996). He received the 2000 ACM SIGCOMM Award "for basic contributions to protocol design ans modeling and for leadership in the development of computer networking in Europe". Since October 1997, he has been Professor Emeritus at the University of Liege.
