Why do Internet service providers use protocols such as PPP and its derivatives PPPoA or PPPoE?
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. Originally designed to work with serial connections, PPP was adopted by ISPs to provide dial-up Internet access.
What protocol does PPP use to identify the network layer protocol?
What protocol does PPP use to identify the Network layer protocol? Explanation: Network Control Protocol is used to help identify the Network layer protocol used in the packet.
What is the use of PPP 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 do you need to know about PPP protocol?
In it, once an LCP establishes a PPP link, the PPP hosts at either end of the connection start a three-way CHAP handshake. However, just one is not enough. Two different handshakes are needed before both sides can fully identify an established PPP link.
How is PPP encapsulated in a lower layer protocol?
PPP frames are encapsulated in a lower-layer protocol that provides framing and may provide other functions such as a checksum to detect transmission errors. PPP on serial links is usually encapsulated in a framing similar to HDLC, described by IETF RFC 1662 .
What does PPP stand for in computer networking?
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 makes PPP different from other WAN protocols?
PPP is a WAN protocol that works at layer 2 by encapsulating frames for transmission over a variety of physical links such as serial cables, cell phones, fiber optic cable among others. it offers many more features as compared to HDLC and it is an open standard. Some of the features that it offers which are not available in HDLC include:
