	Title           : RSVP-TE Signaling Extension For Management Plane To Control Plane LSP Handover In A GMPLS Enabled Transport Network.

In a transport network scenario, where Data Plane connections are
controlled either by a Generalized Multi-Protocol Label Switching
(GMPLS) Control Plane (Soft Permanent Connections - SPC) or by a
Management System (Permanent Connections - PC) may independently
coexist, the ability of transforming an existing PC into a SPC and
vice versa - without actually affecting Data Plane traffic being
carried over it - is a requirement.  The requirements for the
conversion between permanent connections and switched connections in
a GMPLS Network are defined in [RFC5493].

This memo describes an extension to GMPLS RSVP-TE signaling that
enables the transfer of connection ownership between the Management
and the Control Planes.  Such a transfer is referred to as a
Handover.  This document defines all Handover related procedures.
This includes the handling of failure conditions and subsequent
reversion to original state.  A basic premise of the extension is
that the handover procedures must never impact an already established
Data plane.
