Connection-Oriented Architecture
Connection-Oriented Architecture is a network communication model where a dedicated connection is established between two endpoints before data transmission begins, ensuring reliable, ordered, and error-checked delivery. It involves a three-phase process of connection establishment, data transfer, and connection termination, commonly implemented in protocols like TCP (Transmission Control Protocol). This architecture contrasts with connectionless approaches, providing guaranteed delivery at the cost of higher overhead and latency.
Developers should learn and use Connection-Oriented Architecture when building applications that require reliable data transmission, such as file transfers, web browsing (via HTTP/HTTPS over TCP), email services, or real-time communication systems where data integrity is critical. It is essential for scenarios where packet loss, duplication, or out-of-order delivery must be avoided, such as in financial transactions, database replication, or streaming media with quality-of-service guarantees.
