Connection-oriented

In computer networking and telecommunications, 'connection-oriented' describes a communication protocol that establishes a dedicated, end-to-end connection, or circuit, between two communicating endpoints before any data is transmitted. This contrasts with connectionless protocols. It guarantees reliable delivery, in-sequence arrival of data, and often includes mechanisms for flow control and error correction. Think of it like a phone call, where a line is established before conversation, ensuring a continuous and ordered flow of information until disconnection. The protocol negotiates parameters, ensuring the system's efficiency and security.

Connection-oriented meaning with examples

• TCP (Transmission Control Protocol) is a connection-oriented protocol, ensuring data arrives in the same order it was sent. This makes it ideal for applications requiring reliable transfer, such as email or web browsing, where data integrity is paramount.
• Many file transfer protocols rely on connection-oriented systems. When sending a document across a network, the establishing of a connection first to be sure all the data will arrive in order and completely
• VoIP (Voice over Internet Protocol) services often utilize connection-oriented protocols to provide clear and consistent audio streams. A direct connection, like a phone call, is set up for real-time communication, prioritizing quality.
• When you send a text message, a connection-oriented system may be used to send the SMS from your phone to the mobile service provider, ensuring it arrives at the recipient's phone correctly.
• Legacy systems, particularly those involving financial transactions, often utilized connection-oriented protocols for added security and reliability, as it was seen as an ideal approach.
