Overview
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.
Traffic engineering is essential for service provider and Internet
service provider (ISP) backbones. Such backbones must support
a high use of transmission capacity, and the networks must be
very resilient, so that they can withstand link or node failures.
MPLS traffic engineering provides an integrated approach to
traffic engineering. With MPLS, traffic engineering capabilities
are integrated into Layer 3, which optimizes the routing of IP
