PPPoA (RFC 2364)
The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol data
grams over point-to-point links. This document describes the use of ATM Adaptation Layer 5 (AAL5)
for framing PPP encapsulated packets.
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.
