The IESG has received a request from the Common Control and Measurement Plane WG (ccamp) to consider the following document: - 'Framework and Requirements for GMPLS-based control of Flexi-grid DWDM networks' <draft-ietf-ccamp-flexi-grid-fwk-05.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-07-23. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract To allow efficient allocation of optical spectral bandwidth for high bit-rate systems, 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 "frequency slot". In such an environment, a data plane connection is switched based on allocated, variable-sized frequency ranges within the optical spectrum creating what is known as a flexible grid (flexi- grid). This document defines a framework and the associated control plane requirements for the GMPLS-based control of flexi-grid DWDM networks. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-ccamp-flexi-grid-fwk/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-ccamp-flexi-grid-fwk/ballot/ No IPR declarations have been submitted directly on this I-D.
