| Abstract: | From the aspect of the application protocol analysis technique based on content characteristic,a protocol identification method is introduced,which improves the problems that the recognition accuracy is poor when simple protocol features are used to analysis protocols.Based on SmartBits6000C and MPC8572 platform,a finite automaton（FA） to follow the behavior of network protocal is proposed,and regular expression is used to describe a series of normal state transition of protocals analyzed,compared with simple characteristics method,it improves the accuracy of protocol identification and reduces the time consumption overhead. |
