Patent number: 11847108Abstract: A system has data capture devices collecting data from different points in a network. The captured data is written to a data store and is directed to an output. The data from the different data capture devices can be delivered to a data analytics device. As long as the data analytics device is able to keep pace with the data that is directed to the output, that data is used by the analytics device. If the analytics device is not able to keep pace, the data written to the data store is retrieved and is used until the analytics device has caught up.Type: GrantFiled: October 8, 2019Date of Patent: December 19, 2023Assignee: XILINX, INC.Inventors: Steven L. Pope, David J. Riddoch, Matthew Knight
