How do transport layer protocols ensure reliable communication?

Transport layer protocols ensure reliable communication by implementing various mechanisms and techniques. One such mechanism is connection-oriented communication, where a reliable virtual connection is established between the sender and receiver. This connection ensures that data packets are delivered in the correct order, and any lost or corrupted packets are retransmitted. Another technique is error detection and correction, where checksums, cyclic redundancy checks (CRC), or other error detection codes are used to catch and correct errors. Furthermore, flow control mechanisms are implemented to regulate the rate at which data is transmitted, preventing overwhelming the receiver. Transport layer protocols also employ congestion control techniques to manage network congestion and avoid packet loss. By incorporating these mechanisms and techniques, transport layer protocols enhance the reliability of communication and ensure that data is transmitted accurately and efficiently.
