What Does Data Link Control (DLC) Mean?
A data link control is a service that ensures reliable network data communication by managing frame error detection and flow control. DLC is based on the Data Link layer of the OSI model.
DLC handles the following tasks:
- Reliable link packet transmission
- Recovery and error detection during high-layer packet retransmission
- Error framing, which determines start and end packetization via three approaches: length counts, bit-oriented framing and character-oriented framing
DLC character codes are based on standard character codes, such as the American Standard Code for Information Interchange (ASCII). Extended Binary Coded Decimal Interchange Code (EBCDIC) is comprised of hidden characters.
