T3: MPLS - the Importance of Offering the Right Solution at the Right Moment. Timeliness, Benefits, and Deployment from the Origins, to ATM, to Optical Networks

Monday 27 November, 9:00 – 17:00

Derived from a proprietary fast packet switching technique, MPLS (Multi-Protocol Label Switching) has played various roles throughout the years. It has been an approach for the deployment of IP over ATM networks, a solution in utilizing ATM hardware within IP networks, a traffic engineering enhancement for IP, and finally a unifying control plane technology.

This tutorial provides an overview of MPLS from its inspiring principles to its various fields of application. By retracing the evolution of MPLS, the tutorial discusses how it became the next technology promising to satisfy present and future networking needs.

After a presenting the basic mechanisms and operating principles of MPLS, the tutorial discusses the two feature of MPLS that make it a particularly important technology today. The first one, which the tutorial gives particular emphasis to, is related to enabling traffic engineering. First, the limitations of IP with respect to the realization and operation of large backbones are analyzed. Then, traffic engineering features that enable MPLS to overcome such limitations are illustrated together with their underlying mechanisms and protocols.

The second important feature is related to the control plane of MPLS that, on the one hand, is well integrated with the control plane of IP, on the other hand is suitable for deployment on connection oriented networks. For this reason the control plane of MPLS has become a unifying solution for various network technologies. The tutorial first explains the relation between MPLS and different infrastructure technologies, such as Ethernet, PPP, ATM and FR, DWDM, and circuit switching. Then the control plane of MPLS is described discussing how MPLS signaling protocols are used for set-up and restoration of MPLS Label Switched Paths (LSPs), possibly generalized in terms of circuits, optical channels, and sub-lambda channels.

The participants are expected to have basic knowledge on packet switching and the Internet Protocol Suite.
