Title : Label Switched Path Stitching with Generalized Multiprotocol Label Switching Traffic Engineering (GMPLS TE)
Author(s) : A. Ayyangar, et al.
Filename : draft-ietf-ccamp-lsp-stitching-05.txt
Pages : 19

In certain scenarios, there may be a need to combine together several
Generalized Multi-Protocol Label Switching (GMPLS) Label Switched
Paths (LSPs) such that a single end-to-end (e2e) LSP is realized and
all traffic from one constituent LSP is switched onto the next LSP.
We will refer to this as "LSP stitching", the key requirement being
that a constituent LSP not be allocated to more than one e2e LSP.
The constituent LSPs will be referred to as "LSP segments" (S-LSPs).
This document describes extensions to the existing GMPLS signaling
protocol (RSVP-TE) to establish e2e LSPs created from from S-LSPs,
and describes how the LSPs can be managed using the GMPLS signaling
and routing protocols.
It may be possible to configure a GMPLS node to switch the traffic
from an LSP for which it is the egress, to another LSP for which it
is the ingress, without requiring any signaling or routing extensions
whatsoever, completely transparent to other nodes. This will also
result in LSP stitching in the data plane. However, this document
does not cover this scenario of LSP stitching.

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.
