The International Telecommunication Union Telecommunication
standardization sector (ITU-T) has extended its Recommendations
G.694.1 and G.872 to include a new Dense Wavelength Division
Multiplexing (DWDM) grid by defining channel spacings, a set of
nominal central frequencies, and the concept of the "frequency slot".
Corresponding techniques for data-plane connections are known as
"flexi-grid".
Based on the characteristics of flexi-grid defined in G.694.1 and in
RFCs 7698 and 7699, this document describes the Open Shortest Path
First - Traffic Engineering (OSPF-TE) extensions in support of GMPLS
control of networks that include devices that use the new flexible
optical grid.
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.
