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.
The performance objectives associated with TE can be either of the following:
