The present invention defines a method of unbiased policing of data flow in a network device. According to an embodiment of the present invention, the token bucket policer of the network device `permits` (forwards) incoming packets even when the size of the token bucket is less than the size of the incoming packets. Permitting incoming packets that are larger than the token bucket ensures that incoming packets are not dropped because of the size of the incoming packets. Incoming packets are policed by TBP when the magnitude comparison of the token bucket and a predetermined constant value does not comply with the policing scheme defined for the incoming packets. When a packet is `permitted` (forwarded), the size of the token bucket is reduced by an amount equal to the size of the packet.
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.
