Connection-oriented communication refers to a method of data transmission in networking where a virtual connection is established between two or more parties before data transfer begins. Unlike connectionless protocols, which send data independently without prior setup, connection-oriented protocols ensure reliable, ordered, and error-checked communication by maintaining a persistent link throughout the exchange.

Key characteristics of connection-oriented communication include the establishment of a connection phase, data transfer, and a termination phase. During the connection phase, both sender and receiver synchronize, negotiate parameters, and confirm readiness for data exchange. This process often involves handshake mechanisms, such as the three-way handshake used in TCP (Transmission Control Protocol), where acknowledgments ensure successful setup.

Reliability is a defining feature, as connection-oriented protocols detect and correct errors through mechanisms like retransmission of lost packets or acknowledgments for received data. This ensures data integrity and completeness, making it suitable for applications requiring precise delivery, such as web browsing, email, and file transfers.

Common protocols employing connection-oriented principles include TCP, which operates at the transport layer of the OSI model, and ATM (Asynchronous Transfer Mode), used in high-speed networking. These protocols prioritize guaranteed delivery over speed, trading off latency for accuracy.

Connection-oriented communication contrasts with connectionless models like UDP (User Datagram Protocol), which prioritizes speed and efficiency for applications where occasional data loss is tolerable, such as live streaming or online gaming. The choice between the two depends on the application’s requirements for reliability versus performance.
