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 known 
   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.
