HDLC Protocol (High-level Data Link Control Protocol)

HDLC (High-Level Data Link Control) is a bit-oriented code-transparent synchronous data link layer protocol developed by the International Organization for Standardization (ISO). The standard for HDLC is ISO/IEC 13239:2002. HDLC provides both connection-oriented and connectionless service. In HDLC, data is organized into a unit (called a frame) and sent across a network to a destination […]
