9. Reduce Network Congestion-Sometimes the shortest path
between two locations isn't the best one to take, as congestion
has made it less attractive (at least for the time being).
MPLS offers sophisticated traffic engineering options that
enable traffic to be sent over non-standard paths. This
can reduce latency (the delay in sending/receiving data).
It also reduces congestion on the paths that have just been
avoided as a result of traffic engineering.
