What is RSVP-TE ?

What is RSVP-TE (RSVP Traffic Engineering)? 

RSVP-TE refers to a resource reservation protocol that is invented in order to allocate a bandwidth for the individual flows on the network devices.

To say it another way, RSVP-TE are extensions to the RSVP protocol specified in the RFC 3209.

Although, RSVP-TE has been initially invented as a Quality Service Mechanism in an Intserv QoS architecture, it has never been used in modern networks due to scalability problems.

This is also because allocating tremendous number of flows on the networking nodes creates scalability problems. Read more

Why Should You Place Less Emphasis on MPLS Traffic Engineering

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.

What is The Real Reason Behind IP and MPLS Traffic Engineering ?

MPLS traffic engineering has many use cases and it helps to solve the problems in an MPLS enabled networks.

These use cases are in general; QoS guarantee, End to End SLA , Fast reroute, Admission control and so on.

All of them at the end is done for the COST SAVING.

The real reason behind MPLS Traffic engineering is cost saving. This is same for the IP Traffic Engineering as well.

Sometimes as a technical people we tend to forget the real reason behind these technologies and push ourselves to make it work on the network although we could find an easier, simpler, flexible, scalable solutions since we don’t focus on the business problem.

In this article I will show you couple alternative ways for the traffic engineering and then explain why you wouldn’t need MPLS Traffic engineering for the link bandwidth utilization.
