Abstract
As the protocols of Fetion are not public,it is difficult to recognize the Fetion application protocals caused by complex Internet environment and single-package conversation relationship is deficient,three common business protocol proce-dures(text messaging,file transfer and audio/video communication)are parsed on the basis of the basic framework of SIP protocol. The Fetion conversation relationship extraction method based on conversation revivification and protocol identification method of combining port and regular expressions are proposed for quickly locating Fetion service packets in promiscuous raw packets to achieve variety business relationships. Experimental results demonstratd the effectiveness of the method.关键词
