Abstract
Systems, methods, and computer-readable media for performing semantic analysis to identify shadowing events. One or more models of network intents, based at least in part on a priority-ordered listing of rules representing network intents, is received. Each rule comprises a Boolean function of one or more packet characteristics and network fabric conditions, and a corresponding network action. For each given rule of the priority-ordered listing of rules, partial and complete shadowing events are detected based on semantic analysis. The semantic analysis comprises calculating an inverse set that comprises the inverse of the set comprising all rules with a higher or equal priority to the given rule, and then calculating a shadowing parameter that comprises the intersection between the inverse set and the given rule. If the shadowing parameter is equal to zero, a complete shadowing event is detected. If the shadowing parameter is not equal to zero and is not equal to the given rule, a partial shadowing event is detected.
