Question: What Are The Key Features Of The Point To Point Protocol PPP?

What is HDLC and PPP?

HDLC stands for High-level Data Link Control.

PPP stands for Point-to-Point Protocol..

What are the advantages of the PPP protocol?

A key advantage of PPP is that it is an extensible protocol suite. Over the years new protocols have been added to the suite, to provide additional features or capabilities. For example, PPP is designed not to use just a single authentication protocol, but to allow a choice of which protocol is used for this purpose.

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.

Is PPP still used?

Originally, PPP was often used for dial-up connections. 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 PPP Point to Point Protocol and how does it work quizlet?

PPPoE (Point-to-Point Protocol over Ethernet) is a specification for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company’s term for a modem and similar devices.

What are the main principles of PPP?

PPP is based on two main principles:Both parties invest in the project. In a financial sense (manpower, materials budget) and in an expertise-related sense (knowledge, networks).The parties contribute to a societal and often also commercial purpose.

What is the limitation of PPP?

The major limitations include: Not all projects are possible (for various reasons: political, legal, commercial viability, etc.). The private sector may not be interested in a project due to perceived high risks, or it may lack the capacity to implement the project.

Is PPP secure?

PPP is a protocol most widely used by Internet service providers (ISPs) to enable dial up connections to the Internet. PPP facilitates the transmission of data packets between point to point links. … As an authentication protocol, PAP is considered the least secure because the password is not encrypted in transmission.

What are the key features of the Point to Point Protocol?

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

What is the PPP Point to Point Protocol and how does it work?

The Point-to-Point Protocol (PPP) is a data link protocol commonly used in establishing a direct connection between two networking nodes and has largely superseded the older Serial Line Internet Protocol (SLIP) and other standards. It can provide connection authentication, transmission encryption, and compression.

What is number of the RFC that defines the Point to Point Protocol?

RFC 1331 – The Point-to-Point Protocol (PPP) for the Transmission of Multi-protocol Datagrams over Point-to-Point Links.

How does PPP protocol work?

Point-to-Point Protocol or PPP is a layer 2 or data link layer protocol that is used to establish a direct connection between two nodes in a network. … This protocol is used to create a simple link between two peers in a network to transport packets. PPP links are full-duplex and deliver packets in order.

Which two protocols are used in PPP?

PPP Authentication Authentication protocols include the Password Authentication Protocol (PAP), the Extensible Authentication Protocol (EAP), and the Challenge Handshake Authentication Protocol (CHAP). CHAP is the most commonly used.

In telecommunications, a point-to-point connection refers to a communications connection between two communication endpoints or nodes. An example is a telephone call, in which one telephone is connected with one other, and what is said by one caller can only be heard by the other.

Can you apply for both Eidl and PPP?

Yes, you can apply for both. But you can’t use the funds from both loan programs for the same purpose. For the most updated and complete information, read the FAQs on the EIDL and FAQs on the PPP.

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 PPP WAN connection?

A point-to-point connection is one of the most common types of WAN connection. PPP connections are used to connect LANs to service provider WANs, and to connect LAN segments within an organization network. … Simply, when you establish a connection to your ISP (Internet Service Provider) through a modem.

What is encapsulation ppp command?

Enabling PPP on an Interface The encapsulation ppp interface command has no arguments. Remember that if PPP is not configured on a Cisco router, the default encapsulation for serial interfaces is HDLC. … PPP is a Layer 2 encapsulation that supports various Layer 3 protocols including IPv4 and IPv6.

When should I apply for PPP forgiveness?

You must apply for forgiveness within 10 months after the end of the ‘Covered Period. ‘ which is the 24-week period that starts when you received your PPP loan. The lender (i.e. your bank) has 2 months to process your loan forgiveness application then SBA has three additional months to approve your forgiveness.

What is control protocol?

Transmission Control Protocol (TCP) – a connection-oriented communications protocol that facilitates the exchange of messages between computing devices in a network. It is the most common protocol in networks that use the Internet Protocol (IP); together they are sometimes referred to as TCP/IP.

How can I get my PPP forgiven?
