If I input MPLS traffic engineering on any search engines, I will find about 100 articles on the internet providing the same explanations about MPLS traffic engineering.
But unfortunately, nobody ask these questions: do I really need it? What are the reasons behind the implementation of MPLS Traffic Engineering?
Would it worth the time and energy to deploy and learn such a complex technology if there are many easier, resource-friendly alternatives.
In this article, I will explain all the answers to these questions. Undoubtedly, MPLS traffic engineering has many used cases and it helps to solve numerous problems in an MPLS enabled networks.
