In computer networking, the Point-to-Point Protocol over ATM (PPPoA) is a layer 2 data-link protocol typically used to connect domestic broadband modems to ISPs via phone lines. It is used mainly with DOCSIS and DSL carriers, by encapsulating PPP frames in ATM AAL5. Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) is specified by ...
Point-to-Point Protocol. Point-to-Point 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. [1] It can provide loop detection, authentication, transmission encryption, [2] and data compression.
The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP 's IP network, and from there to the rest of the Internet.
PPPoX ( PPP over X) designates a family of encapsulating communications protocols implementing Point-to-Point Protocol . Specific implementations: PPPoE: PPP over Ethernet – which can use 802.1q VLANs. PPPoA: PPP over ATM. PPTP: PPP encapsulated over GRE with a parallel control connection and some optional encryption.
For example, if the hosts agree to transfer IP, a sender can pass each datagram directly to AAL5 to transfer; nothing needs to be sent besides the datagram and the AAL5 trailer. The chief disadvantage of such a scheme lies in duplication of virtual circuits : a host must create a separate virtual circuit for each high-level protocol if more ...
The Serial Line Internet Protocol (SLIP) [1][2] is an encapsulation of the Internet Protocol [a] designed to work over serial ports and router connections. It is documented in RFC 1055. On personal computers, SLIP has largely been replaced by the Point-to-Point Protocol (PPP), which is better engineered, has more features, and does not require ...

Point-to-Point Protocol daemon (PPPD) is the daemon that implements Point-to-Point Protocol (PPP). PPP is used to manage network connections between two nodes on Unix-like operating systems. It is configured using command-line arguments and configuration files. While it has initially been used to manage only dial-up access, it is also used to ...
