The present invention defines a method and apparatus to extend class-based queuing (CBQ) with multiple 'behavioral' queues per class, to include a dynamic weighting mechanism between these queues. The packets are forwarded from the behavioral queues according to the weighting assigned to each queue. The weighting for packet scheduling of the queues is adjusted to account for additional flow going through the queues. The weight of a queue is controlled relative to the weight available to other queues. When a flow is reclassified, the queue weights is readjusted accordingly. Well behaved flows experience low delay and can thus achieve a fair bandwidth allocation without having to have multiple packets queued to compete with non-adaptive aggressive flows.
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.
