Abstract
A method and apparatus are provided for generating Generic Mapping Procedure (GMP) stuff/data decisions, which avoids brute force modulo arithmetic and is efficient for hitless adjustment of ODUFIex (G.7044) in an Optical Transport Network (OTN). Addition operations are used, rather than multiplication operations, to facilitate faster and less computationally expensive calculation of data/stuff decisions, based on calculated residue values. Residue values are logically arranged in rows to facilitate residue calculation, such as based on relationships with previously calculated residue values. This method is also applicable for mapping and de-mapping Constant Bit Rate (CBR) clients into and from an ODUk carrier.
