PPP
PPPis the Point-to-Point-Protocol. The successor to SLIP, PPP provides router- to-router and host-to-network connections over both synchronous and asynchronous circuits.
PPPoA (RFC 2364)
The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol datagrams 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
A permanent virtual circuit is a connection-oriented, permanent leased-line circuit between end stations on a network over a separate ATM circuit.
RFC
Request for Comments is the document series, begun in 1969, that 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
This is a 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. The second method does higher-layer protocol multiplexing implicitly by ATM Virtual Circuits (VCs).
