Three Way Handshake, Research Paper Example

The ‘TCP three way handshake’ is a method incorporated by the TCP to establish a data session or a TCP session (TCP three-way handshake.2007). Likewise, the session establishment is carried out between the client and the server that may initiate or accept the TCP connection. As the TCP is connection oriented protocol, a reliable connection is required to ensure reliable data connectivity (Three-way handshake.2007). Moreover, the ‘TCP three way handshake’ is considered to the standardized method of creating TCP data connections (Beardsley & Qian, 2010). However, in order to establish a data connection, a device must transmit a SYN and receives ACK from the other device. However, in a logical perspective, there are total four control messages that correspond between the two devices trying to establish connectivity. Likewise, SYN and ACK messages are not enough, as they are sending simultaneously by configuring relevant bits of both SYN+ACK. For this reason, there are total 3 messages and therefore called as a three way handshake procedure. The semantics of these messages passing between a client and a server as shown in fig 1.1, demonstrates the procedure and steps required for a three way handshake. Moreover, the fig 1.1 also demonstrates the traditional method of establishing a data connection between a server and a client. Likewise, the three messages transmitted for establishing a connection within each process along with the transition of devices that were in a ‘Closed’ state initially and changed to ‘Established’ status after the successful connection creation.
