Abstract
In general, techniques are described for efficient management of ring networks with a system of two network devices. The first network device of the ring network is designated as an adjacent selective forwarding (ASF) device, and the second network device is designated as a master device. The master device monitors the ring network to determine whether a fault has occurred in the ring network and transmits via a secondary port of the master device a network status message to the ASF device based on the determination of whether the fault has occurred. The ASF device determines a status of the ring network based on the network status message and selectively forwards data traffic to the master network device based on the determination of the status. As a result, the master device more efficiently utilizes network resources by not consuming processor or memory resources to prevent traffic loops.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
