MPLS Basic

Nº 1105
DATE: CALL
PRICE NIS: 2120 + VAT
DURATION: 2 Days

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?

The seminar is built for Technical people of Telecom Service Providers as well as Manufacturers of packet switching equipment.

Prerequisities:

Basic knowledge of data communications and routing is expected from the participants
