Abstract

   This memo discusses the applicability of "Extensions to RSVP
   (Resource ReSerVation Protocol) for LSP Tunnels".  It highlights the
   protocol's principles of operation and describes the network context
   for which it was designed.  Guidelines for deployment are offered and
   known protocol limitations are indicated.  This document is intended
   to accompany the submission of "Extensions to RSVP for LSP Tunnels"
   onto the Internet standards track.

1.0 Introduction

   Service providers and users have indicated that there is a great need
   for traffic engineering capabilities in IP networks.  These traffic
   engineering capabilities can be based on Multiprotocol Label
   Switching (MPLS) and can be implemented on label switching routers
   (LSRs) from different vendors that interoperate using a common
   signaling and label distribution protocol.  A description of the
   requirements for traffic engineering in MPLS based IP networks can be
   found in [2].  There is, therefore, a requirement for an open, non-
   proprietary, standards based signaling and label distribution
   protocol for the MPLS traffic engineering application that will allow
   label switching routers from different vendors to interoperate.

   The "Extensions to RSVP for LSP tunnels" (RSVP-TE) specification [1]
   was developed by the IETF MPLS working group to address this
   requirement.  RSVP-TE is a composition of several related proposals
