This presentation argues for the viability of metric-based traffic engineering (TE) in a pure IP network, as a simple alternative to MPLS tunnel-based TE. An overview of the steps required to perform metric-based TE are presented, with some special attention to demand estimation. A particular TE goal, reducing worst-case failure utilisation, is described formally. Metric-based TE is compared to alternatives in a study conducted on currently existing IP networks, using this criterion as a judge of performance.
