Abstract: PURPOSE: A packet inspection method in an underwater sound sensor and a device thereof are provided to analyze a packet flow and a network performance by collecting and analyzing a plurality of packets in real time. CONSTITUTION: A token bite filtering unit and a separator byte filtering unit individually filter token bytes or separator bytes(S105). A packet header and footer analysis unit extracts payload data, a data packet header, and footer information which use the filtered token byte or separator byte(S107). A pattern determination unit extracts a pattern of the data packet by using the extracted payload data, footer information, and data packet header(S109). The pattern determination unit determines whether the extracted pattern is matched with a predetermined pattern(S111). A packet analysis unit analyzes information related to the corresponding data packet when the extracted pattern is matched with the predetermined pattern(S113). [Reference numerals] (AA) Start; (BB) End; (S101) Capturing a plurality of data packets transmitted from UW-ASN in real time; (S103) Inputting the captured data packets in the form of stream; (S105) Filtering token-byte or separator-byte included in the packet stream; (S107) Extracting a data packet header, payload data, and footer information using the token-byte or the separator-byte; (S109) Extracting the pattern of the data packet using the extracted information; (S111) Is the extracted pattern matched to a predetermined pattern?; (S113) Analyzing information related to the data packet
