FYI This update addresses editorial issues reported by IESG (Jari Arkko) and GEN-ART (Francis Dupont) review. Lou -------- Original Message -------- Subject: [mpls] I-D Action:draft-ietf-mpls-gmpls-lsp-reroute-05.txt Date: Thu, 10 Sep 2009 05:15:01 -0700 (PDT) From: Internet-Drafts@ietf.org To: i-d-announce@ietf.org CC: mpls@ietf.org A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Multiprotocol Label Switching Working Group of the IETF. Title : PathErr Message Triggered MPLS and GMPLS LSP Reroute Author(s) : L. Berger, et al. Filename : draft-ietf-mpls-gmpls-lsp-reroute-05.txt Pages : 12 Date : 2009-09-10 This document describes how Resource ReserVation Protocol (RSVP) PathErr Messages may be used to trigger rerouting of Multi-Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) point-to-point Traffic Engineering (TE) Label Switched Paths (LSPs) without first removing LSP state or resources. Such LSP rerouting may be desirable in a number of cases including, for example, soft-preemption and graceful shutdown. This document describes the usage of existing Standards Track mechanisms to support LSP rerouting. In this case, it relies on mechanisms already defined as part of RSVP-TE and simply describes a sequence of actions to be executed. While existing protocol definition can be used to support reroute applications, this document also defines a new reroute-specific error code to allow for the future definition of reroute application-specific error values.
