Abstract
A system and method for reducing the number of cycles used in CAM lookup. A network comprises a plurality of network devices connected to a router. The router comprises a media access controller which is effective to receive an input packet and a packet processor which is effective to receive the input packet from the media access controller and to extract data stored in the input packet. The router further comprises a CAM which is effective to receive the data stored in the input packet from the packet processor, a PRAM, a control processor and a bus. The control processor controls the packet processor and the CAM so that the packet processor extracts a destination address from the input packet and forwards the destination address to the CAM. The packet processor extracts a source address from the input packet and forwards the source address to the CAM. The CAM performs a lookup of the destination and source addresses in parallel. The packet processor extracts miscellaneous information, a source protocol address, and a destination protocol address from the received packet and the CAM performs a lookup of the miscellaneous information, the source protocol address, and the destination protocol address at the same time.

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.
