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.

Multicast Design – Podcast

Efficient data transfer, optimised resource usage , simplified configuration, optimum bandwidth usage are the main characteristics of Multicast.

In the diagram below; unicast and multicast flows are shown.

From the source, if same packet will be sent , with unicast transport you send two copies. Read more
