 RSVP-TE Signaling Extension for LSP Handover from the Management Plane
       to the Control Plane in a GMPLS-Enabled Transport Network

Abstract

   In a transport network scenario, Data Plane connections controlled by
   either a Generalized Multiprotocol Label Switching (GMPLS) Control
   Plane (Soft Permanent Connections - SPC) or a Management System
   (Permanent Connections - PC) may independently coexist.  The ability
   of transforming an existing PC into an 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 RFC 5493.

   This memo describes an extension to GMPLS Resource Reservation
   Protocol - Traffic Engineering (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
   connection.
