Traffic Engineering Limitations<br />
• TE cannot create capacity<br />
•e.g. “V-O-V” topologies allow no scope strategic TE if optimizing for<br />
failure case<br />
Only two directions in each “V” or “O” region – no routing choice for<br />
minimizing failure utilization<br />
• Other topologies may allow scope for TE in failure case<br />
•As case study later demonstrates<br />
