Abstract
Methods and apparatus to track network topology changes are disclosed. An example apparatus includes machine readable instructions, and a processor to execute the instructions to perform operations. The operations include, in response to a reporting message generated by a software defined controller containing topology change information corresponding to a topology change event scheduled to occur at a future time, store, in a topology database, a pre-validation data record reflecting the occurrence of the topology change event. The pre-validation data record indicates the occurrence is not validated. In addition, a validation seeking message is generated to validate occurrence of the topology change event and is transmitted to a network device to be subject to the topology change event after the future time. In response to a validation message from the network device, a post-validation data record is stored in the topology database.
