5 Using MPLS TE Management
MPLS TE Management overview
TE and MPLS
Network congestion is one of the major problems that can degrade your network performance. It may
occur either when network resources are inadequate or load distribution is unbalanced.
TE can best utilize network resources and avoid uneven load distribution by real-time monitoring traffic
and traffic load on each network element. The purpose is to dynamically tune traffic management
attributes, routing parameters and resources constraints.
To implement TE, you can use interior gateway protocols (IGPs) or Multiprotocol Label Switching (MPLS).
Because IGPs are topology-driven and include only network connectivity, they fail to present some
dynamic factors such as bandwidth and traffic characteristics. MPLS TE remedies this IGP disadvantage,
