US Patent 10382265 Reversible yang-based translators

In general, techniques are described for generating reversible mappings for management systems. The management system may include an interface and a processor. The interface may communicatively couple the management system to network devices. The processor may generate a data structure that represents each expression of a forward mapping as a separate node of the data structure. The processor may also translate one or more of the expressions represented as the separate nodes in the data structure to corresponding one or more negated expressions so as to form a reverse mapping. Further, the processor may apply the reverse mapping to the low-level configuration of the first network device to obtain the high-level configuration.
