Generalized Multiprotocol Label Switching (GMPLS) can be used to
control a wide variety of technologies including packet switching
(e.g., MPLS), time division (e.g., Synchronous Optical Network /
Synchronous Digital Hierarchy (SONET/SDH) and Optical Transport
Network (OTN)), wavelength (lambdas), and spatial switching (e.g.,
incoming port or fiber to outgoing port or fiber). In some of these
technologies, network elements and links may impose additional
routing constraints such as asymmetric switch connectivity, non-
local label assignment, and label range limitations on links. This
document describes Open Shortest Path First (OSPF) routing protocol
extensions to support these kinds of constraints under the control
of GMPLS.
This document is a product of the Common Control and Measurement Plane Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
