Patent number: 10733245Abstract: 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.Type: GrantFiled: January 3, 2019Date of Patent: August 4, 2020Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Heng Wang, Robert J. Ferro, Leah L. Zhang, Luis Figueroa

Patent number: 10210258Abstract: 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.Type: GrantFiled: October 23, 2017Date of Patent: February 19, 2019Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Heng Wang, Robert J.

Patent number: 9998382Abstract: A process and system for user-controlled configuration of an Internet protocol network. The user may supply input for generating a network classification profile, which includes a number of classes of service (COSs) for prioritizing network traffic, including video transmission. A quality of service (QOS) may be measured and compared with a COS for video transmission. Depending on the measured QOS, a network alert may be issued and a priority of packets associated with the COS for video transmission may be increased.Type: GrantFiled: June 1, 2015Date of Patent: June 12, 2018Assignee: AT&T Intellectual Property I, L.P.Inventors: Robert J. Ferro, Luis Figueroa, David H. Lu, Chen Yui Yang

Patent number: 9798810Abstract: 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.Type: GrantFiled: September 30, 2014Date of Patent: October 24, 2017Assignee: AT&T Intellectual Property I, L.P.Inventors: Heng Wang, Robert J.

Patent number: 8638672Abstract: Systems and techniques for improved error detection in data communication. A sending station encodes unencoded data to create an encoded message and passes the encoded data to transmission elements for transmission to a destination receiver. At the same time, error detection is performed using copies of the unencoded data and the encoded message. The encoded message is decoded using a decoding procedure identical to that to be used by the destination receiver. The copy of the unencoded data is compared to the decoded copy of the encoded message, and if the copy of the unencoded data does not match the decoded copy, the presence of an error is identified and error recovery procedures are performed.Type: GrantFiled: December 18, 2007Date of Patent: January 28, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: George Sultana, Robert J.
