PPP Standards
(Page 3 of 3)
Feature Protocols
These protocols define optional features
used with PPP, such as compression and encryption (Table 28).

Description
|
1962
|
The PPP
Compression Control Protocol (CCP)
|
Defines a mechanism for compressing
data sent over PPP links to improve performance. This standard describes
how compression is negotiated between two devices on a PPP link. It
is used in conjunction with several compression algorithms that actually
do the compression of data.
|
1968
|
The
PPP Encryption Control Protocol (ECP)
|
Defines a mechanism
for encrypting data sent over PPP links to improve performance. This
standard describes how encryption is negotiated between two devices.
It is used with several encryption algorithms.
|
1989
|
PPP Link
Quality Monitoring
|
Defines a protocol that lets
PPP devices generate reports to each other about the quality of the
link.
|
1990
|
The
PPP Multilink Protocol (MP)
|
Defines a method
for running PPP over a set of aggregated links, allowing two devices
to use multiple low-bandwidth links as a single, high-bandwidth virtual
link.
|
2125
|
The PPP
Bandwidth Allocation Protocol (BAP) / The PPP Bandwidth Allocation Control
Protocol (BACP)
|
Defines two support protocols
that manage the allocation of bandwidth in links aggregated using the
PPP Multilink Protocol (MP).
|
Applications and Miscellaneous
These protocols describe how PPP
can be adapted to run over particular types of links, or that don't
really fit into any of the other groups above. They are shown in Table 29.

Description
|
1618
|
PPP over
ISDN
|
Describes application particulars
for running PPP over ISDN links.
|
1973
|
PPP
in Frame Relay
|
Describes how
PPP may be modified to run over Frame Relay at layer two.
|
2290
|
Mobile-IPv4
Configuration Option for PPP IPCP
|
Defines changes to the PPP Internet
Protocol Control Protocol (IPCP) to support Mobile IP.
|
2364
|
PPP
Over AAL5
|
Defines a method
for sending PPP frames over AAL5 (ATM); commonly called PPPoA.
|
2516
|
A Method
for Transmitting PPP Over Ethernet (PPPoE)
|
Defines a technique for encapsulating
PPP frames over Ethernet (PPPoE).
|
2615
|
PPP
over SONET/SDH
|
Discusses how
to encapsulate PPP frames over SONET/SDH links.
