A system assigns network traffic flows to appropriate queues and/or queue servicing algorithms based upon one or more flow parameters contained in reservation requests associated with the traffic flows. The system may be disposed at an intermediate network device within a computer network. The intermediate network device includes a reservation engine, a packet classification engine, an admission control entity, a traffic scheduler, and a flow analyzer. The flow analyzer includes or has access to a memory that is preprogrammed with one or more heuristic sets for use in evaluating the flow parameters of reservation requests. When a reservation request that includes one or more flow parameters characterizing the bandwidth and/or forwarding requirements of the anticipated traffic flow is received, the flow analyzer applies the heuristic sets. Depending on which set of heuristics, if any, the parameters satisfy, the flow analyzer selects the appropriate queue and/or queue servicing algorithm for the flow.
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.
