    摘要： 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.

    摘要： Methods and apparatus to track network topology changes are disclosed. An example topology tool to track a change to a network topology includes a message processor to, in response to a reporting message generated by a software defined network controller, identify a unique identifier (UID) associated with a network element to be subject to a topology change event, where the reporting message including topology change information corresponding to the topology change event scheduled to occur at a future time. A database search tool is to search a first topology database for a first post-confirmation data record corresponding to the UID and in response to the first post-confirmation data record missing from the first topology database, search a second topology database for a first pre-confirmation data record corresponding to the UID. A database controller is to generate a second pre-confirmation data record in response to the first pre-confirmation data record missing from the second topology database.

    摘要： Methods and apparatus to track network changes are disclosed herein. An example method to track a network topology includes, in response to a reporting message including topology change information corresponding to a topology change event, generating a confirmation-seeking message based on the topology change information to confirm the topology change event and updating a topology data set representing the network topology based on a response to the confirmation-seeking message. Further disclosed methods include generating a pre-confirmation data record that reflects the topology change information contained in the reporting message, and storing the pre-confirmation data record in a pre-confirmation topology database.
