3.2.2 default TCP communication using time Three-way Handshake Three-way Handshake is a way to send packets that can solve the problem in the story, but is redundant packets in this way, the need to build communication channels, before starting the data transfer. However, control packets that are used to negotiate the variable values for various communications may occur as residues in the system. Make the configuration sequence number, there are issues such as creating a channel to communicate between host 1 and host 2. Starting from host 1. Start the connection by sending packets to CR (Connection Request) to the host variable will have the value 2, which is for communication, including the serial number and the slot number is communicated with. The recipient is to host 2 sends ACK (Acknowledge), back to the host, but if packets from the sender, lost their way and copies of packets is also a system to reach the recipient at a later time, it will make the creation of communication channels, not because there is a different variable values do not match.The use of force are not handshake Three-way the sender and the recipient must determine the initial value of the sequence number is the same number. This method makes it possible to share with you how to organize work together (Synchronization). Instead of using the method to save the time Figure 7-1 shows the steps to start working from the host 1 to host 2 host 1 to choose Muhammad talismanic sequence number is "x", and send CONNECTION REQUEST packets to the host 2 host 2 CONNECTION packets ACCEPTED by acknowledgement which will accept a sequence number "x" with a "y" sequence number declaration is then host 1, it will host two options through a field for control in the first data packets that were sent.
