I don’t know how many of you have heard about this term called “PPPoE” which stands for Point-to-Point-Protocol over Ethernet. Even though this article is not intended to explain in detail about this protocol, in order to have a general understanding let’s go through the common concepts of PPP and PPPoE briefly.

PPPoE as a derivate of PPP
Point-to-Point Protocol (PPP) is a data link protocol used to establish a direct connection between two nodes. It can provide connection authentication, transmission encryption and compression. PPP is also used over internet access connections. Two derivatives of PPP, Point-to-Point Protocol over Ethernet (PPPoE) and Point-to-Point Protocol over ATM (PPPoA) are most commonly used by Internet Service Providers (ISPs) to establish a Digital Subscriber Line (DSL) internet service connection with customers. The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating PPP frames inside ethernet frames.

Establish a PPPoE connection
This would normally require a authenticated DSL connection via phone line, trunk line, optical fibre etc. So I would assume that you have Read More »
