In a transport network scenario, where Data Plane connections
controlled either by GMPLS (Soft Permanent Connections - SPC) or by
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 valuable option. This applies especially when
a GMPLS based Control Plane is first introduced into an existing
network and there may be the need, from a Carrier point of view, to
pass under GMPLS control existing connections already set up over
Data Plane. In other terms, such operation could be seen as a way of
transferring the ownership and control of an existing and in-use Data
Plane connection between the Management Plane and the Control Plane,
leaving its Data Plane state untouched.
This memo provides a minor extension to GRSVP-TE signaling protocol,
within GMPLS architecture, to enable such connection ownership
transfer and describes the proposed procedures.

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.
