GMPLS OSPF-TE Extensions in support of Flexi-grid DWDM networks
draft-ietf-ccamp-flexible-grid-ospf-ext-07.txt
Abstract
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 a set of nominal central
frequencies, channel spacings, and the concept of the "frequency
slot". Corresponding techniques for data-plane connections are know
as flexi-grid.
Based on the characteristics of flexi-grid defined in G.694.1, RFC
7698 and 7699, this document describes the OSPF-TE extensions in
support of GMPLS control of networks that include devices that use
the new flexible optical grid.
Status of this Memo
This Internet-Draft is submitted to IETF in full conformance with
the provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
