1) Functions of 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.
