[Acronym] for the __PPP__ __o__ver __E__thernet protocol, defined in RFC:2516.

A simple protocol, designed to allow discovery of [AccessConcentrator]s and end-point services they provide.

The five packet types used by [PPPoE] are:
;; PADI : PPPoE Active Discovery Initiation
;; PADO : PPPoE Active Discovery Offer
;; PADR : PPPoE Active Discovery Request
;; PADS : PPPoE Active Discovery Session-confirmation
;; PADT : PPPoE Active Discovery Terminate

Their definitions and use can be found in the RFC.

Once the discovery protocol has done the setup, the session protocol actually passes the [PPP] data between
the AccessConcentrator and the client.

[ Roaring Penguin Software | http://www.roaringpenguin.com/ ] have a [Free] [implementation of the protocol | http://www.roaringpenguin.com/products/rp-pppoe/] that works under [Linux], [NetBSD]/[FreeBSD], and [Solaris].  The [Debian] package is __pppoe__.

As of 2.4.something, the Linux kernel has kernel-mode [PPPoE] support. The [Kernel] [PPPoE] driver typically yields lower [CPU] load than the Roaring Penguin client.

See [LinuxPPPoENotes] for more details.
