- 2-4 day(s)
- Aimed At
-
This course is aimed at the IT and telecommunications professionals, managers, sales engineers, proposal writers, and others who need to understand the MPLS technology in order to meet customer needs or design MPLS networks.
- Prerequisites
-
Those wishing to take this course should have a basic knowledge of TCP/IP and telecommunications networks.
- Course in a Nutshell
-
MPLS is a technology that utilizes special labels to speed packets through networks and thus achieve faster performance and greater throughput. It also facilitates Quality of Service (QoS) implementation and Virtual Private Networks (VPNs) to name just a couple of its benefits. MPLS does not replace IP but builds on it.
This course deals with all of the key issues of understanding, designing, and implementing MPLS in IP networks. We will begin with a quick review of IP routing and the OSI stack. We will then study the basics of MPLS label switching and continue with applications including VPNs, Quality of Service (QoS), and Traffic Engineering. We conclude with a study of advanced and emerging applications for MPLS including multicast, circuit emulation, and hierarchical LSPs. We will finish up with discussion of MPLS marketing opportunities and real-world network designs. Examples and short exercises are interspersed throughout the course.
- Customize It!
-
Let us know your reason for studying MPLS so we can customize the course to your specific needs. If you do not possess prior knowledge of IP or basic communications network technology, the course can be expanded to four days to cover these topics.
