Connection-Oriented Networking
Connection-oriented networking is a communication model where a dedicated connection is established between two devices before data transmission begins, ensuring reliable, ordered, and error-checked delivery of data packets. It involves a three-phase process: connection establishment, data transfer, and connection termination, commonly implemented in protocols like TCP (Transmission Control Protocol). This approach contrasts with connectionless networking, providing guaranteed delivery at the cost of higher overhead and latency.
Developers should learn and use connection-oriented networking when building applications that require reliable data transmission, such as web servers, file transfers, email systems, or real-time communication tools where data integrity and order are critical. It is essential for scenarios where packet loss or errors must be minimized, such as in financial transactions, database replication, or streaming services that demand consistent performance.
