                           Domain Subobjects
   for Resource Reservation Protocol - Traffic Engineering (RSVP-TE)

Abstract

   The Resource Reservation Protocol - Traffic Engineering (RSVP-TE)
   specification and the Generalized Multiprotocol Label Switching
   (GMPLS) extensions to RSVP-TE allow abstract nodes and resources to
   be explicitly included in a path setup.  Further, Exclude Route
   extensions to RSVP-TE allow abstract nodes and resources to be
   explicitly excluded in a path setup.

   This document specifies new subobjects to include or exclude
   Autonomous Systems (ASes), which are identified by a 4-byte AS
   number, and Interior Gateway Protocol (IGP) areas during path setup.
