What is MPLS Traffic Engineering?

Japan

Explicitly Managing the Data Flow
Route Chosen By
IP Routing Protocol• Traffic engineering

RouteSpecified By
MPLS-TE

Aligning traffic flows toresources
Optimize link utilization• Fast reroute
Fast, local, link and nodeprotection

FR Edge Node• Guaranteed bandwidth
Hard end-to-end bandwidth FR Edge Nodeand delay guarantees
Conventional IP Routing is destination based and is based on simple link costs.
Bandwidth availability is not taken into accountSome links may be underutilized while others are congested
MPLS-TE supports explicit routing
Lets you use paths other than IGP shortest path
Allows unequal-cost load sharing© 2003, Cisco Systems, Inc. All rights reserved.
