There are many scenarios in which extensions to Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) are required for error notication in Generalized Multiprotocol Label Switching (GMPLS) User-Network Interface (UNI). This document outlines these scenarios and specifies the required extensions to RSVP-TE. Although the GMPLS-UNI reference model is used to describe requirements and solutions in the document, the proposed extensions are equally applicable to other deployment scenarios such as inter-domain RSVP- TE.
