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

RFC 3210 Applicability Statement for Extensions December 2001

submitted to the IETF MPLS working group. It contains all the necessary objects, packet formats, and procedures required to establish and maintain explicit label switched paths (LSPs). Explicit LSPs are foundational to the traffic engineering application in MPLS based IP networks. Besides the traffic engineering application, the RSVP-TE specification may have other uses within the Internet.

This memo describes the applicability of the RSVP-TE specifications [1]. The protocol’s principles of operation are highlighted, the network context for which it was developed is described, guidelines for deployment are offered, and known protocol limitations are indicated.

This applicability statement concerns only the use of RSVP to set up unicast LSP-tunnels. It is noted that not all of the features described in RFC2205 [3] are required to support the instantiation and maintenance of LSP-tunnels. Aspects related to the support of other features and capabilities of RSVP by an implementation that also supports LSP-tunnels are beyond the...
