The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.
PPP is used to manage network connections between two nodes on Unix-like operating systems. It is configured using command-line arguments and configuration files . While it has initially been used to manage only dial-up access , it is also used to manage broadband connections such as DSL , if Point-to-Point Protocol over Ethernet (PPPoE) or ...
RFC 2364 describes Point-to-Point Protocol over ATM (PPPoA) as a method for transmitting PPP over ATM Adaptation Layer 5 , which is also a common alternative to PPPoE used with DSL. PPP, PPPoE and PPPoA are widely used in WAN lines. PPP is a layered protocol that has three components: [4]
This is because it uses headers that are short so imposes minimal overheads, 2 bytes for PPP and 8 bytes for PPPoA (with the RFC2364 VC-MUX option) = 10 bytes. [ 2 ] [ 3 ] [ 4 ] It also avoids the issues that PPPoE suffers from, related to sometimes needing to use an IP MTU of 1492 bytes or less, lower than the standard 1500 bytes.
Almost all network operating systems support PPP with PAP, as do most network access servers. PAP is also used in PPPoE, for authenticating DSL users. As the Point-to-Point Protocol (PPP) sends data unencrypted and "in the clear", PAP is vulnerable to any attacker who can observe the PPP session. An attacker can see the users name, password ...
These suggestions are designed to help with broadband connections only. If you don't have broadband, you'll need to try other steps to fix problems with a dial-up internet connection.
A DSL modem, which is type of customer-premises equipment. The WAN interface of this device, in this case the DSL port, could expose CWMP to the internet service provider . Technical Report 069 ( TR-069 ) is a document by the Broadband Forum that specifies the CPE WAN Management Protocol ( CWMP ).
