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. CCNA INTRO Exam Certification Guide.

SDLC was mainly used by IBM mainframe and midrange systems; however implementations exist on many platforms from many vendors. The use of SDLC (and SNA) is becomming more and more rare, mostly replaced by IP-based protocols or being tunneled through IP (using AnyNet or other technologies).
