Question

What are the advantages and disadvantages of hdlc protocol?

Answer 1

Advantages and Disadvantages of PPTP. HDLC (High-Level Data Link Control) is a communication protocol used at the data link layer of PPP encapsulation uses a variant of the ISO High Level Data Link Control (HDLC) protocol to encapsulate multi-protocol datagrams as the payload of PPP frames.

Answer 2

Answer:

Advantages of hdlc protocol:

• It also supports serial transmission.
• HDLC communication mode is both synchronous and asynchronous.
• It uses directional mode TWA and TWS.
• It also supports both point-to-point and point-to-multipoint configurations.
• It follows the sliding window flow control protocol.
• For content errors, it uses the CRC method.
• It uses the flagframe identifier for framing.
• When framing a flag frame separator.
• Multi-bit information field in framing.
• This is followed by ZERO padding for frame transparency.

Disadvantages of hdlc protocol:

• Current control and error checking are not available in frame relay. The upper layer protocols should take care of this.
• Packets incur additional delay with each node they pass through.
• This includes data and processing costs for each packet.
