MPLS (Multi-Protocol Label Switching)

Description

This course provides an in-depth study of the MPLS technology, including the theory and configuration, network design issues, operations, VPN, and traffic engineering. We will start with an overview of conventional routing and how it compares to MPLS routing. We will then learn about the underlying concepts, features, functions, benefits, and applications of MPLS. We will the frame-mode MPLS, the concept of MPLS labels, label stack and different label formats, the label distribution process between LSRs, the loop detection and prevention mechanisms in MPLS, MPLS architecture, MPLS VPN, MPLS QoS, and MPLS traffic engineering. We will conclude with an exploration of the future trends related to the MPLS technology.

Target group

Those with a technical background who are familiar with data networking concepts and have the need to understand the evolving MPLS-based systems

Prerequisites

Routing knowledge (OSPF/IS-IS and BGP/MP-BGP)equivalent to our course IP Routing

Other

This course is available as scheduled training and the presentation is given in English or Swedish. The course is mixing theory and practical exercises. We can also give this course as on-site training. If you are interested in customized education, don’t hesitate to contact us for further information.
