Link control procedure refers to a set of protocols and techniques employed in communications systems to ensure reliable and efficient data transmission over a link or a network. It involves the management and coordination of data flow across the link, making use of specific procedures and algorithms.
The link control procedure often begins with establishing a connection between two endpoints in the network. This typically involves a process called link establishment, where the parties involved exchange control messages to negotiate various parameters and establish a reliable channel for data transfer.
Once the link is established, the link control procedure manages the transmission of data packets over the connection. This includes techniques such as error detection and error correction protocols to ensure the integrity of the transmitted data. If errors are detected, the link control procedure may initiate procedures for retransmission or request for the retransmission of specific data packets.
Furthermore, link control procedures are responsible for flow control, which regulates the rate at which data is transmitted based on the recipient's ability to process it. It helps prevent data overload or congestion, ensuring that the link is not overwhelmed and can efficiently transmit data.
Overall, link control procedures play a crucial role in maintaining the reliability, efficiency, and integrity of data transmission over a link or network. They ensure that data is transmitted accurately, detect and correct errors, and manage the flow of data to optimize the link's performance.
