PPPoE (RFC 2516)
This document describes how to build PPP sessions and encapsulate PPP
packets over Ethernet. PPP over Ethernet (PPPoE) provides the ability to
connect a network of hosts over a simple bridging access device to a remote
Access Concentrator.
Protocol
A protocol is a set of rules for interaction agreed upon between multiple parties
so that when they interface with each other based on such a protocol, the
interpretation of their behavior is well defined and can be made objectively,
without confusion or misunderstanding.
PVC
Permanent Virtual Circuit, connection-oriented permanent leased line circuit
between end-stations on a network over a separate ATM circuit.
RFC
Request for Comments. The document series, begun in 1969, which describes
the Internet suite of protocols and related experiments. Not all RFCs describe
Internet standards, but all Internet standards are written up as RFCs.
RFC 1483
Multi-protocol encapsulation over AAL-5. Two encapsulation methods for carrying
network interconnect traffic over ATM AAL-5. The first method allows multiplexing
of multiple protocols over a single ATM virtual circuit. The protocol of a carried
PDU is identified by prefixing the PDU by an IEEE 802.2 Logical Link Control
(LLC) header. This method is in the following called "LLC Encapsulation". The
second method does higher-layer protocol multiplexing implicitly by ATM Virtual
Circuits (VCs). It is in the following called "VC Based Multiplexing".
Router
A system responsible for making decisions about which of several paths network
(or Internet) traffic will follow. To do this, it uses a routing protocol to gain
information about the network and algorithms to choose the best route based on
several criteria known as "routing metrics.
