Abstract
Hashing and pattern matching are used in an information processing system to process incoming messages from a network such as an Ethernet-based network. Using hashing and pattern matching increases the efficiency of message acceptance and rejection without increasing software-based processor tasks. A hash function and a pattern matching function are performed on a message received by an information processing system, and the message is selectively accepted based on at least one of a hash result and a pattern matching result. The incoming message can be searched for the existence of patterns and the absence of the patterns. The incoming message can be searched for the existence of multiple patterns. The results of pattern matching can be used not only for acceptance and rejection of messages, but also for other post-receipt tasks such as selective storage of incoming messages according to identified relative priorities or absolute criticality of messages having particular pattern matches.

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.
