Title : Reoptimization of Multiprotocol Label Switching
(MPLS) Traffic Engineering (TE) loosely routed
Label Switch Path (LSP)

This document defines a mechanism for the reoptimization of loosely
routed MPLS and GMPLS (Generalized Multiprotocol Label Switching)
Traffic Engineering LSPs. A loosely routed LSP is defined as one
that does not contain a full explicit route identifying each LSR
along the path of the LSP at the time it is signaled by the ingress
LSR. Such an LSP is signaled with no ERO, with an ERO that contains
at least one loose hop, or with an ERO that contains an abstract
node that is not a simple abstract node (that is, an abstract node
that identifies more than one LSR). This document proposes a
mechanism that allows a TE LSP head-end LSR to trigger a new path re-
evaluation on every hop having a next hop defined as a loose or
abstract hop and a mid-point LSR to signal to the head-end LSR that a
better path exists (compared to the current path in use) or that the
TE LSP must be reoptimized because of some maintenance required on
the TE LSP path.
The proposed mechanism applies to the cases of intra and inter-domain
(IGP area or Autonomous System) packet and non-packet TE LSPs
following a loosely routed path.

In the body type:

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
