A method, apparatus, and computer program product for dynamic bandwidth allocation in a packet switched network having a ring architecture is disclosed. The method includes monitoring an occurrence of a contention of resources at a participating node and its neighboring nodes on the network. In response to a monitored occurrence of the contention of resources, bandwidth is dynamically allocated according to a fairness algorithm. Dynamically allocating bandwidth resolves contention of resources in a fair manner within given fairness constraints while enabling a prescribed maximum utilization of available bandwidth between the nodes. Lastly, the fairness algorithm generates fairness criteria in response to states that are local to the participating node and states obtained from the neighboring nodes.
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.
