Connection Establishment

Connection-oriented protocols typically use a 3-way handshake to establish a connection. One side of a connection initiates an active connection request by sending an initial request packet to the other side. This side responds to a valid request with a connection response packet. Finally, the initiator should respond with an ACK, completing the 3-way handshake and connection establishment phase.

Connection establishment packets are surveyed by timers. If no response is received during a specified amount of time, the packets are retransmitted.

Look how a normal 3-way handshake works and how lost packets are retransmitted after a timeout by selecting a method in the drop-down-menu!
