Note: RFC Descriptions applying to DSL Protocols and Encapsulations
RFC2684, Multiprotocol Encapsulation over ATM LLC/SNAP - two encapsulation
methods for carrying network interconnect traffic over AAL type 5 over ATM. The
first method allows multiplexing of multiple protocols over a single ATM virtual
connection whereas the second method assumes that each protocol is carried over
a separate ATM virtual connection.
RFC2516, Point-to-Point Protocol over Ethernet PPPoE - provides the ability to
connect a network of hosts over a simple bridging access device to a remote
Access Concentrator by encapsulating PPP packets over Ethernet.
RFC2364, Point-to-Point Protocol over ATM PPPoA - provides the ability to establish
a point-to-point relationship between peers using ATM Adaptation Layer 5 (AAL5)
for framing PPP encapsulated packets.
RFC2153, Point-to-Point Protocol - provides a standard method for transporting
multi-protocol datagrams over point-to-point links. PPP defines an extensible Link
Control Protocol (LCP) for establishing, configuring, and testing the data-link
connection; and a family of Network Control Protocols (NCPs) for establishing and
configuring different network-layer protocols.
RFC1994, Challenge Handshake Authentication Protocol (CHAP) - the next best
password scheme over PAP—a three-way handshake using a public domain
encryption algorithm to securely pass user information across the link to
authenticate a user with the server.
RFC1994, Password Authentication Protocol (PAP) - the basic internet password
scheme—sends the user name and password in the clear to the server.
