Abstract
Official abstract text for this publication.
A system matches frame counter values between a timing master and one or more slave devices in a synchronous network. To detect synchronization losses, a timing master counts transmitted frames of a continuous data stream. When a synchronization loss occurs, the timing master transmits a message to the slave devices that includes a synchronization frame counter value. The message synchronizes the frame counter value of the timing master to the frame counter value of the slave devices.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for matching frame counter values of a timing master and at least one slave device in a synchronous network having a ring topology, comprising: counting frames of a continuous data stream transmitted by the timing master through a master frame counter of the timing master; counting one or more of the frames of the continuous data stream received from the timing master by the at least one slave device through a local slave frame counter of the at l…
