Course Overview
The course starts with the issues that drove the transition of packet networks towards MPLS, we describe the advantages of MPLS and the MPLS basic components and concepts. We then go into details regarding the handling of Label Switched Path (LSP), maintenance and protection issues and QoS models. We present various signaling protocols (LDP, RSVP-TE). We conclude presenting other MPLS related topics such as Pseudowire Emulation (PWE) and its use in VPLS applications, and the work being done on MPLS Transport Profile (MPLS-TP). During the course we present examples of networks using the MPLS tools.
Who should attend?
