Difference Between HDLC and PPP

The major difference between HDLC and PPP is that HDLC is the bit oriented protocol, while PPP is the character-oriented protocol. The HDLC and PPP are the crucial data link layer protocols used in WAN (wide area network) where the HDLC can also be implemented with PPP for the efficient results.

What is PPP and HDLC?

HDLC stands for High-level Data Link Control. PPP stands for Point-to-Point Protocol. ... HDLC is a bit oriented protocol. PPP is a byte oriented protocol.

What are the advantages of PPP over HDLC?

Advantages of PPP (3.2.

PPP includes many features not available in HDLC: The link quality management feature, as shown in Figure 3-20, monitors the quality of the link. If too many errors are detected, PPP takes the link down. PPP supports PAP and CHAP authentication.

What is HDLC used for?

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.

How HDLC PPP and Frame Relay encapsulation is different from each other?

Unlike HDLC and PPP, Frame Relay does not require a dedicated point to point link, as it is a packet-switched technology. Therefore, it does not require dedicated leased lines which means it can be more cost-effective as a WAN technology.

Is PPP still used?

PPP (Point-to-point protocol) is a WAN protocol that is often used on point-to-point links. Nowadays it's still used for DSL with PPPoE (PPP over Ethernet) and PPPoA (PPP over ATM). ... One of the advantages of still using PPP is that it allows authentication through PAP and CHAP.

What is the use of PPP protocol?

In computer networking, Point-to-Point Protocol (PPP) is a data link layer (layer 2) communication protocol between two routers directly without any host or any other networking in between. It can provide connection authentication, transmission encryption, and data compression.

What are the three components of PPP?

PPP is comprised of three main components:

• A method for encapsulating multi-protocol datagrams.
• A Link Control Protocol (LCP) for establishing, configuring, and testing the data-link connection.
• A family of Network Control Protocols (NCPs) for establishing and configuring different network-layer protocols.

What are the advantages of PPP protocol?

PPP advantages:

• Ensure the necessary investments into public sector and more effective public resources management;
• Ensure higher quality and timely provision of public services;
• Mostly investment projects are implemented in due terms and do not impose unforeseen public sectors extra expenditures;

What is PPP LCP?

In computer networking, the Link Control Protocol (LCP) forms part of the Point-to-Point Protocol (PPP), within the family of Internet protocols. In setting up PPP communications, both the sending and receiving devices send out LCP packets to determine the standards of the ensuing data transmission.

How does HDLC work?

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.

What layer is HDLC?

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.

Is HDLC WAN?

Like the two other WAN protocols mentioned in this article, HDLC is a Layer 2 protocol (see OSI Model for more information on Layers). HDLC is a simple protocol used to connect point to point serial devices. ... HDLC would be running over the WAN, between the two locations.
