MPLS Traffic Engineering and Enhancements

Last Updated: February 28, 2006
Multiprotocol Label Switching (MPLS) traffic engineering software enables an MPLS backbone to
replicate and expand upon the traffic engineering capabilities of Layer 2 ATM and Frame Relay
networks. MPLS is an integration of Layer 2 and Layer 3 technologies. By making traditional Layer 2
features available to Layer 3, MPLS enables traffic engineering. Thus, you can offer in a one-tier
network what now can be achieved only by overlaying a Layer 3 network on a Layer 2 network.
