Traffic Engineering with MPLS (Networking Technology。screen-shot-2015-08-13-at-4-46。MPLS Traffic Engineering (TE) Explained。Traffic Engineering By Roess Roger P Prassas Elena S McShane。Design, configure, and manage MPLS TE to optimize network performanceAlmost every busy network backbone has some congested links while others remain underutilized. That's because shortest-path routing protocols send traffic down the path that is shortest without considering other network parameters, such as utilization and traffic demands. Using Traffic Engineering (TE), network operators can redistribute packet flows to attain more uniform distribution across all links. Forcing traffic onto specific pathways allows you to get the most out of your existing network capacity while making it easier to deliver consistent service levels to customers at the same time.
