HDLC Protocol Overview Blog Information Technology, Blogging

High-Level Data Link Control ( HDLC) 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 . HDLC (High-level Data Link Control) is a group of protocols or rules for transmitting data between network points (sometimes called nodes ). In more technical terms, HDLC is a bit-oriented, synchronous data link layer protocol created by the International Organization for Standardization ( ISO ). The standard for HDLC is ISO/IEC 13239:2002.

HDLC, or High-level Data Link Control, is a standard synchronous communication protocol at the data-link layer of the Open Systems Interconnection reference model that is used for wide area network synchronous serial connections over leased lines. What is HDLC (High-level Data Link Control)? High-Level Data Link Control (HDLC) basically provides reliable delivery of data frames over a network or communication link. HDLC provides various operations such as framing, data transparency, error detection, and correction, and even flow control. Primary stations simply transmit commands that contain address of secondary stations. High-level Data Link Control (HDLC) is a group of communication protocols of the data link layer for transmitting data between network points or nodes. Since it is a data link protocol, data is organized into frames. A frame is transmitted via the network to the destination that verifies its successful arrival. Cisco HDLC ( cHDLC) is an extension to the High-Level Data Link Control (HDLC) network protocol, and was created by Cisco Systems, Inc. HDLC is a bit-oriented synchronous data link layer protocol that was originally developed by the International Organization for Standardization (ISO).

High Level Data Link Control is a protocol, which operates at the data link layer. The HDLC protocol embeds information in a data frame that allows devices to control data flow and correct errors HDLC is an ISO Standard developed from the Synchronous Data Link Control (SDLC) standard proposed by IBM Operates at the data link layer HDLC is a layer two protocol that provides encapsulation method for serial link. Serial link and Ethernet link both use different encapsulation methods for data transmission. Serial link cannot carry the frame formatted with Ethernet encapsulation and vice versa Ethernet link cannot carry the frame formatted through the Serial encapsulation.

HIGH LEVEL DATA LINK CONTROL PROTOCOL 1 HDLC

HDLC - Short for High-level Data Link Control, a transmission protocol used at the data link layer (layer 2) of the OSI seven layer model for data communications. The HDLC protocol embeds information in a data frame that allows devices to control data flow and correct errors. HDLC is an ISO standard developed from the Synchronous Data Link Control (SDLC) standard proposed by IBM in the 1970's. HDLC is a common WAN protocol that operates at the data-link layer and transmits data between network endpoints. HDLC is based on IBM's SDLC protocol and was developed by the International Organization for Standardization (ISO). HDLC data is packed into frames and sent across the network using delivery-verification procedures. 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.

The HDLC protocol is a data-link layer protocol that provides for many various services of the transfer of network-layer packets either in connection-oriented or connectionless mode, so providing or not providing a reliable data transfer. In the connection-oriented mode of operation it can work either as a go-back-N or a selective-repeat protocol. High-Level Data Link Control (HDLC) is the successor to SDLC. HDLC adds error correction and flow control, as well as two additional modes (ARM and ABM). The three modes of HDLC are • Normal Response Mode (NRM) —Secondary nodes can transmit when given permission by the primary. •
