This time we will handle the basic traffic engineering within a MPLS network. This technique allows network admin to manipulate the traffic and fully utilize the subscribed bandwidth or circuits.
Traffic engineering within a MPLS network can be more accurate and convenience than in a typical TCP/IP network, because TE are happened at the MPLS level only, which would not affect the base of the whole network topology. If manipulate traffic at the IP level, everything running on top of IP level will be affected.
The network topology for this testing is listed below.
