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.
