RSVP Traffic Engineering
MPLS Traffic Engineering (TE) extends RSVP to support several unique capabilities.
By coupling RSVP and MPLS, LSPs can be signaled along explicit paths with specific resource reservations. Additional RSVP objects have been defined to provide TE extensions. These objects include the Label Request, Label, Explicit Route, Record Route, and Session Attribute. Extreme's RSVP-TE implementation supports all of these TE objects.
