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： Devices, computer-readable media and methods are disclosed for managing path utilizations for telecommunication network tunnels. For example, a processor deployed in a telecommunication network may receive a request from a router of the telecommunication network for a tunnel to a destination in the telecommunication network, send a response to the router that includes at least one path comprising the tunnel through the telecommunication network to the destination, receive a trap message from the router that includes a confirmation that the at least one path is utilized by the router, and update at least one record for the at least one path in response to the trap message, where the at least one record indicates a status of a utilization of the at least one path.

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.

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.
