MPLS Traffic Engineering

Wprowadza do routingu w sieci

MPLS koncepcję routingu wg.

polityki

IP/MPLS

MPLS TE obsługuje również

mechanizmy routingu zgodnie z

nałożonymi ograniczeniami

(ang. constrained-

based routing ) oraz kontrolę

administracyjną i mechanizmy

ochrony tras

Rozszerzenia w protokołach

IGP ( ISIS i OSPF ) pozwalają

rozgłosić atrybuty połączeń , a

RSVP-TE – ustanowić LSP

TE LSP
