NETWORK MESSAGE PROCESSING USING PATTERN MATCHING

摘要

Pattern matching is used in an information processing system to process incoming messages from a network such as an Ethernet-based network to aid in filing such messages in memory and the selective stashing of such messages in cache. Pattern matching increases the efficiency of message acceptance and rejection without increasing software-based processor tasks. 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, and such as selective direction of messages to different processing domains within a multi-processor computer system according to the pattern matches.
