US Patent 7861004 System and method for analyzing data traffic

A method of analyzing data traffic includes receiving a request at a data analysis system to store a string related to header information associated with a data packet. The method also includes applying a hash function to the string, thereby obtaining a 32-bit intermediate, and applying another hash function to the 32-bit intermediate, thereby obtaining a hash number. Further, the method includes storing the string in an array position corresponding to the hash number, when the array position is empty.
