Abstract

This document describes procedures and protocol extensions for the use of Resource Reservation Protocol-Traffic Engineering (RSVP-TE) signaling in Multiprotocol Label Switching-Traffic Engineering (MPLS-TE) packet networks and Generalized MPLS (GMPLS) packet and non-packet networks to support the establishment and maintenance of Label Switched Paths that cross domain boundaries.

Status of This Memo

   This document specifies an Internet standards track protocol for the    Internet community, and requests discussion and suggestions for    improvements.  Please refer to the current edition of the "Internet    Official Protocol Standards" (STD 1) for the standardization state    and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document describes procedures and protocol extensions for the    use of Resource Reservation Protocol-Traffic Engineering (RSVP-TE)    signaling in Multiprotocol Label Switching-Traffic Engineering    (MPLS-TE) packet networks and Generalized MPLS (GMPLS) packet and    non-packet networks to support the establishment and maintenance of    Label Switched Paths that cross domain boundaries.

   For the purpose of this document, a domain is considered to be any    collection of network elements within a common realm of address space    or path computation responsibility.  Examples of such domains include    Autonomous Systems, Interior Gateway Protocol (IGP) routing areas,    and GMPLS overlay networks.
