Header length: It is the length of the TCP header and can vary from 20 to 60.Ī major section of this TCP packet analysis is the flag section of a packet which gives further in-depth information about the packet.Acknowledgment number: It contains the byte length of data received.Next sequence number: It is the sum of the sequence number and the segment length of the current packet.

Sequence number: It is a method used by Wireshark to give particular indexing to each packet for tracking packets with ease.TCP segment length: It represents the data length in the selected packet.Destination port: This is the port of the destination server.Source port: This is the port of your host network used for communication.Let’s look at each one of them and their significance: Now to examine a packet closely we shall select a packet and in the expert view in the packet detail section just below the packet list we shall be having the TCP parameters as you can see in the below diagram. ACK, SYN, SYN-ACK is listed on their respective side. You can observe these three steps in the first three packets of the TCP list where each of the packet types i.e. Net-Centric Computing in Cloud Computing.Frequency-Hopping Spread Spectrum in Wireless Networks.Top 50 Penetration Testing Interview Questions and Answers.Two Factor Authentication Implementation Methods and Bypasses.Information Security and Computer Forensics.
