Using MPLS in traffic engineering

Traffic engineering is the task of routing network traffic to avoid points of congestion and make efficient use of high bandwidth interfaces.

When used as an application of MPLS, traffic engineering involves creating LSPs that make the best use of available network resources; that is, traffic-engineered LSPs. This section explains the process of creating traffic-engineered LSPs.

Creating traffic-engineered LSPs involves the following tasks:
  • Gathering information about the network
  • Using the gathered information to select optimal paths through the network
  • Setting up and maintaining the paths
