    abstract =  {This document defines a framework and the associated control plane requirements for the GMPLS based control of flexi-grid DWDM networks. To allow efficient allocation of optical spectral bandwidth for high bit-rate systems, the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) is extending the standard {[}G.694.1{]} to include the concept of flexible grid: a new DWDM grid has been developed within the ITU-T Study Group 15, by defining a set of nominal central frequencies, smaller channel spacings and the concept of "frequency slot". In such environment, a data plane connection is switched based on the allocated, variable- width optical spectrum frequency slot.},
