Dial-up Internet connections typically use PPP protocol. PPPoA is a method for running PPP protocol over ATM. PPPoA… • • offers service providers similar billing and access control with a presence in dial-up services.• provides session authentication using Password Authentication Protocol (PAP).• provides session authentication using Challenge Handshake Authentication Protocol (CHAP).• achieves session accounting and conservation of bandwidth by closing down unused sessions.• allows the IAD/Router and ISP link to easily negotiate network parameters.
PPP over ATM. A standard protocol for encapsulating PPP frames in AAL5 (ATM Adaptation Layer 5). PPPoA is used in broadband Internet connection, using ADSL or cable modem. Also see DSL and cable modem.
One of the two types of PPP interfaces you can define for a Virtual Circuit(VC), the other being PPPoE. You can only define one PPPoA per VC.
PPP over ATM is the standard delivery method for ADSL servers.
Stands for point-to-point protocol over ATM. It is a method of encapsulating your data for transmission to a far point. Basically, a DSL modem pumping ATM is internal to the computer, rather than being a short Ethernet cable away. Originally designed for dialup lines, it is being used by DSL providers to solve the problems they get managing an open DSL network, e.g. IP address shortages, broadcasts not meant for you appearing on your local IP address, and other difficulties inherent in large bridged networks.
PPPoA is the acronym for Point-to-Point Protocol over ATM.
Point-to-Point Protocol over ATM (RFC 2364) is one of the PPP protocols being used by some DSL providers. This is really a device specific driver, and in many respects quite different from PPPoE. A hardware device, i.e. a combination modem/router, is one alternative if this is the only option available to you.
(Point-to-Point Protocol over Asynchronous Transfer Mode) - ATM is a high-speed switching technique used to transmit high volumes of voice, data, and video traffic.
