Please Whitelist This Site?

I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)

If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.

If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.

Thanks for your understanding!

PPP Standards
(Page 3 of 3)

Feature Protocols

These protocols define optional features used with PPP, such as compression and encryption (Table 28).


Table 28: PPP Feature Protocol Standards

RFC Number

Standard Name

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.


Table 29: PPP Application and Miscellaneous Standards

RFC Number

Standard Name

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.
