Pattern Matching in Multiple Streams [article]

Raphael Clifford, Markus Jalsenius, Ely Porat, Benjamin Sach
2012 arXiv   pre-print
We investigate the problem of deterministic pattern matching in multiple streams. In this model, one symbol arrives at a time and is associated with one of s streaming texts.  ...  The task at each time step is to report if there is a new match between a fixed pattern of length m and a newly updated stream.  ...  Introduction We introduce a new set of problems centered on pattern matching in multiple streaming texts.  ...

Hardware Architecture of a Parallel Pattern Matching Engine

Meeta Yadav, Ashwini Venkatachaliah, Paul D. Franzon
2007 2007 IEEE International Symposium on Circuits and Systems  
Several network security and QoS applications require detecting multiple string matches in the packet payload by comparing it against predefined pattern set.  ...  The algorithm optimizes pattern matching process through two key innovations of parallel pattern matching using incoming content filter and multiple character matching using trie pruning.  ...  The incoming content filter splits the packet payload into multiple subs-streams that could lead to a possible match, these multiple streams are then passed to dedicated pattern matching engines that match  ...
