Ethernet. 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.
In computing, the Challenge-Handshake Authentication Protocol (CHAP) is an authentication protocol originally used by Point-to-Point Protocol (PPP) to validate users. CHAP is also carried in other authentication protocols such as RADIUS and Diameter. Almost all network operating systems support PPP with CHAP, as do most network access servers.
Password Authentication Protocol (PAP) is a password -based authentication protocol used by Point-to-Point Protocol (PPP) to validate users. [1] PAP is specified in RFC 1334. Almost all network operating systems support PPP with PAP, as do most network access servers. PAP is also used in PPPoE, for authenticating DSL users.
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. PPP is used over many types of physical networks ...
EtherType is a two- octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames. EtherType is also used as the basis ...
Internet Protocol over Ethernet (IPoE) is a method of delivering an IP payload over an Ethernet -based access network or an access network using bridged Ethernet over Asynchronous Transfer Mode (ATM) without using PPPoE. It directly encapsulates the IP datagrams in Ethernet frames, using the standard RFC 894 encapsulation.
In computer networking, Internet Protocol Control Protocol (IPCP) is a Network Control Protocol (NCP) for establishing and configuring Internet Protocol over a Point-to-Point Protocol link. IPCP is responsible for configuring the IP addresses as well as for enabling and disabling the IP protocol modules on both ends of the point-to-point link.
Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers. 7. Application layer. 6. Presentation layer. 5. Session layer. 4. Transport layer.
