Point-to-point protocol
• In networking, the Point-to-Point Protocol
(PPP) is a data link protocol commonly
used in establishing a direct connectionused in establishing a direct connection
between two networking nodes. It can
provide connection authentication,
transmission encryption and compression.

• PPP is used over many types of physical
networks including serial cable, phone line,
cellular telephone, radio links, and fiber
optic links.
• PPP is also used over Internet access• PPP is also used over Internet access
connections (now marketed as
"broadband").

Most encapsulated forms of PPP is Point-to-Point Protocol over Ethernet (PPPoE) which
used most commonly by Internet Service
Providers (ISPs) to establish an Internet
service connection with customers.

• RFC 2516 describes Point-to-Point Protocol
over Ethernet (PPPoE) as a method for
transmitting PPP over Ethernettransmitting PPP over Ethernet

• The PPPoE (Point to Point Protocol overEthernet) protocol provides extensive usermanagement, network management andaccounting benefits to ISPs and networkadministrators. Currently PPPoE is usedmainly by ISPs to control client connectionsfor Ethernet networks. PPPoE is anfor Ethernet networks. PPPoE is anextension of the standard Point to PointProtocol (PPP). The difference betweenthem is expressed in transport method:PPPoE employs Ethernet instead of serialmodem connection.

Transition Phases
![Page 9: MikroTikCertified Network Associate 2015-2016 By M.Sc. I.T … · 2016-04-18 · University of Babylon, IT College Information Network Dep., Third Class, Second Semester MTCNA Course](https://reader033.fdocuments.us/reader033/viewer/2022050122/5f52a60b927c3202800c079d/html5/thumbnails/9.jpg)
• Dead: In the dead phase the link is not being used.
There is no active carrier (at the physical layer) and the
line is quiet.
• Establish: When one of the nodes starts the
communication, the connection goes into this phase. In
Transition Phases
communication, the connection goes into this phase. In
this phase, options are negotiated between the two
parties. If the negotiation is successful, the system goes
to the authentication phase (if authentication is
required) or directly to the networking phase. The link
control protocol packets, that will be discussed shortly,
are used for this purpose. Several packets may be
exchanged here.
![Page 10: MikroTikCertified Network Associate 2015-2016 By M.Sc. I.T … · 2016-04-18 · University of Babylon, IT College Information Network Dep., Third Class, Second Semester MTCNA Course](https://reader033.fdocuments.us/reader033/viewer/2022050122/5f52a60b927c3202800c079d/html5/thumbnails/10.jpg)
• Authenticate: The authentication phase is optional; the two
nodes may decide, during the establishment phase, not to skip
this phase. However, if they decide to proceed with
authentication, they send several authentication packets. If the
result is successful, the connection goes to the networking phase;
otherwise, it goes to the termination phase.
Transition Phases
• Network: In the network phase, negotiation for the network
layer protocols takes place. PPP specifies that two nodes establish
a network layer agreement before data at the network layer can be
exchanged. The reason is that PPP supports multiple protocols at
the network layer. If a node is running multiple protocols
simultaneously at the network layer, the receiving node needs to
know which protocol will receive the data.

• Open: In the open phase, data transfer takes place.
When a connection reaches this phase, the exchange of
data packets can be started. The connection remains in
this phase until one of the endpoints wants to terminate
the connection.
Transition Phases
• Terminate: In the termination phase the connection is
terminated. Several packets are exchanged between the
two ends for house cleaning and closing the link.
