Design of HDLC Controller Using VHDL
In this paper, the authors explore a High-level Data link control published by International Standards Organization (ISO). HDLC is one of the most enduring and fundamental standards in Communications. HDLC is in itself a group of several protocols or rules for transmitting data between network points. The HDLC protocol also manages the flow or pace at which the data is sent. The data is organized into a unit called a frame. HDLC controllers are devices, which executes the HDLC protocol. Some of the key operations of the HDLC protocol implemented are handling bit oriented protocol structure and formatting data as per the packet switching protocol, it includes Transmitting and receiving the packet data serially and providing the data transparency through zero insertion and deletion.
