Synchronous Data Link Control

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. SDLC was mainly used by IBM mainframe and midrange systems; however, implementations exist on many platforms from many vendors.
