OSI model in time for TCP/IP protocol Overview 1.1 OSI model in time for TCP/IP protocol introduce It was
2、repose International Organization for Standardization suggest to whereas extend arisen, it broke into seven layer into to that OSI model (open system interconnection reference model). The overdone bulkiness, intricacy incur know clearly heap criticism of the is ISO constitutive OSI reference model.

Either these attack summarize arisen include： One: source address cheat(source address spoofing) or IP cheat(IP spoofing)； Two: source routing select cheat(source routing spoofing)； Three: rip attack(rip attacks)； Four: discriminate attack(authentication attacks)；
