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
