Synchronous Data Link Control
From Wikipedia, the free encyclopedia
Synchronous Data Link Control (SDLC) is a computer communications protocol. It is the layer 2 protocol for IBM's Systems Network Architecture (SNA). SDLC supports multipoint links as well as error correction. It also runs under the assumption that an SNA header is present after the SDLC header.[1]
It was the basis for the HDLC and ADCCP protocols, which added features such as the balanced response mode.
