Technical Summary
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.
