Traffic Engineering and MPLS TE
Traffic engineering
Network congestion is one of the major problems that can degrade your network backbone
performance. It may occur either when network resources are inadequate or when load distribution is
unbalanced. Traffic Engineering (TE) is intended to avoid the latter situation where partial congestion
may occur as the result of inefficient resource allocation.
TE can make best utilization of network resources and avoid non-even load distribution by real-time
monitoring traffic and traffic load on each network elements to dynamically tune traffic management
attributes, routing parameters and resources constraints.
