Why do we need Point to Point Protocol?

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. It can provide authentication, encryption, and compression. This protocol is used to create a simple link between two peers in a network to transport packets.

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

PPP has three main components: a way to encapsulate multiprotocol datagrams; a Link Control Protocol to establish, configure and test the data-link connection; and a group of network control protocols that establish and configure different types of network-layer protocols.

Why are network control protocols used in PPP?

Network Control Protocol (NCP) is a set of protocols forming a part of Point − to − Point Protocol (PPP). NCPs are used for negotiating the parameters and facilities for the network layer. For every higher-layer protocol supported by PPP, one NCP is there.

What do you mean by Point to Point Protocol?

Point-to-Point Protocol (PPP) is a TCP/IP protocol that is used to connect one computer system to another. Computers use PPP to communicate over the telephone network or the Internet. A PPP connection exists when two systems physically connect through a telephone line. You can use PPP to connect one system to another.

What is a point to point link in networking?

A point-to-point connection is a permanent direct communication link between two parties. A point-to-point connection has to be installed by a provider and made available to the customer in order to be used for communication purposes.

What is meant by point-to-point connection?

What is the meaning of point-to-point in networking?

A Point to Point Network is a private data connection securely connecting two or more locations for private data services. A point to point network is a closed network data transport service which does not traverse the public Internet and is inherently secure with no data encryption needed.

Which of the following protocols is replaced by Point-to-Point Protocol?

PPP is commonly used as a data link layer protocol for connection over synchronous and asynchronous circuits, where it has largely superseded the older Serial Line Internet Protocol (SLIP) and telephone company mandated standards (such as Link Access Protocol, Balanced (LAPB) in the X. 25 protocol suite).

What is PPP protocol?

The PPP Protocol. In reality, PPP is a collection of three protocols: a datagram encapsulation protocol; an LCP, or Link Control Protocol, enabling testing and communication configuration; a collection of NCPs, or Network Control Protocols, allowing integration control of PPP within the protocols of the upper layers.

Where is point to point protocol used?

In computer networking , Point-to-Point Protocol is a data link layer 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. PPP is used over many types of physical networks, including serial cable, phone line, trunk line, cellular telephone, specialized radio links, and fiber optic links, such as SONET. Internet service providers have used PPP for customer di

What is the point to Point Protocol?

Point-to-point protocol. In networking, the Point-to-Point Protocol is a data link protocol commonly used in establishing a direct connection between two networking nodes. It can provide connection authentication, transmission encryption, and compression.

What is the point of PPP?
