Connection-oriented vs. connectionless protocols
- [Instructor] TCP and UDP utilize the two connection types: connection oriented and connectionless. Transmission Control Protocol or TCP is considered connection oriented. This means it uses a system to provide reliable delivery of traffic. TCP utilizes a system known as the three-way handshake to establish connections. Before a connection is considered established, both hosts need to send and receive a SYN packet and an ACK packet. Technically, this could be four separate messages, but one of these transmissions can include both a SYN and an ACK. Thus, we have a three-way handshake. First, the client host will initiate the interaction to the server by sending a SYN packet. The client then waits for a response. Second, the server responds to the client by sending a SYN/ACK packet. Third and last, the client then completes the handshake by returning an ACK. The ACK packet is part of the positive acknowledgement…
