High-Level Data Link Control - Wikipedia
WebHigh-Level Data Link Control (HDLC) is a communication protocol used for transmitting data between devices in telecommunication and networking. Developed by the International Organization for Standardization (ISO), it is defined in the standard ISO/IEC 13239:2002. HDLC ensures reliable data transfer, allowing one device to understand data sent ...
What is HDLC and what is its role in networking? - TechTarget
WebHDLC (High-level Data Link Control) is a group of protocol s or rules for transmitting data between network points (sometimes called node s). In HDLC, data is organized into a unit (called a frame ) and sent across a network to a destination that verifies its successful arrival. The HDLC protocol also manages the flow or pacing at which data ...
High-Level Data Link Control (HDLC) Encapsulation
Web3 days ago · HDLC Encapsulation Protocol : We know that each of frames of HDLC includes at least six to seven fields like start/end flag field, control field, information field, FCS (Frame Check Sequence) field. Standard HDLC Protocol contains six fields. Whereas on the other hand, Cisco HDLC (cHDLC) contains one extra protocol field.

WebNov 24, 2014 · High-Level Data Link Control: A high-level data link control (HDLC) is a protocol that is a bit-oriented synchronous data link layer. HDLC ensures the error-free transmission of data to the proper destinations and controls the data transmission speed. HDLCs can provide both connection-oriented and connectionless services.

WebHDLC. HDLC is a group of data link (Layer 2) protocols used to transmit synchronous data packets between point-to-point nodes. Data is organized into addressable frames. This format has been used for other multipoint-to-multipoint protocols, and inspired the HDLC-like framing protocol described in RFC 1662. HDLC uses a zero-insertion/deletion ...
