Various net users are usually stuck up with making the choice of what type of protocol would be best to use with their connection.
When it comes to PPPoE and PPPoA, various queries, research, experiments are done between them, which sometimes goes beyond these 2 protocols.
It can be noted that both these protocols offer ISP i.e. internet service providers, the potential to rollout broadband use.
As it gives the opportunity to the end-user to confirm or verify to a server before getting network access, giving them security for the same.
Key Takeaways
- PPPoE (Point-to-Point Protocol over Ethernet) and PPPoA (Point-to-Point Protocol over ATM) are protocols for establishing internet connections.
- PPPoE operates over Ethernet networks and is widely used in DSL and cable internet services.
- PPPoA functions over ATM networks and is more common in older DSL infrastructures.
PPPoE vs PPPoA
The difference between PPPoE and PPPoA is that PPPoE (Point-to-Point Protocol over Ethernet) expresses the essential features of PPP frames within the Ethernet frames succinctly whereas PPPoA (Point-to-Point Protocol over ATM) expresses the essential features of frames within AAL5 succinctly.

Comparison Table
| Parameter of Comparison | PPPoE | PPPoA |
|---|---|---|
| Full form | PPPoE stands for Point-to-Point Protocol over Ethernet | PPPoA stands for Point-to-Point Protocol over ATM. |
| Definition | Point-to-Point Protocol over Ethernet (PPPoE) combines PPP to the LAN link-layer protocol. This in turn enables the clients to attach to a web of hosts on top of a bridge or access concentrator. | The Point-to-Point Protocol over ATM (PPPoA) used in various computer or PC networkings, is mainly a two layer data-link protocol usually accustomed to connect domestic broadband modems to ISPs through phone lines. |
| Packages used | PPPoE is commonly employed in lower packages | PPPoA is commonly employed in enterprise packages |
| Most used | PPPoE is more commonly used than PPPoA. | PPPoA is less commonly used than PPPoE. |
| Which is preferred most | PPPoA has way more negatives than PPPoE, hence it outweighs the sole negatives in PPPoE. Hence, PPPoE ought to be the most preferred and famous to be selected by each suppliers and end-users. | As seen already, PPPoA has many more negatives than PPPoE, hence PPPoA is less popular or less preferred to use. |
What is PPPoE?
PPPoE stands for Point-to-Point Protocol over Ethernet. The main aim of Point-to-Point Protocol over Ethernet (PPPoE) is that it combines PPP to the LAN link-layer protocol.
Point-to-Point Protocol over Ethernet is a sort of web-network protocol that expresses the essential features of PPP frames within the local area network frames.
Moreover, PPPoE is generally utilized in ISP’s lower packages as PPPoE is usually utilised to perform in lower bandwidth throughput rate.
PPPoE is maybe the foremost common protocol used once connecting to the net. It provides better support, amazing compatibility, better brand visibility, great familiarity at the user’s end and more revenue opportunities.
What is PPPoA?
PPPoA stands for Point-to-Point Protocol over ATM. The main aim of The Point-to-Point Protocol over ATM (PPPoA) used in various computer or PC networkings, is mainly a two layer data-link protocol usually accustomed to connect domestic broadband modems to ISPs through phone lines.
The word ATM stands for Asynchronous Transfer Mode. This means a sort of shift with the help of time division multiplexing in an asynchronous manner i.e. not simultaneous or concurrent in time.
PPPoA is alleged to own less operating or running costs in comparison to PPPoE, making it thus quicker than PPPoE. In spite of this, the distinction in speed is sort of insignificant or minor for the main users.
Use of an ATM ensures that very little, fixed-length packets are used in comparison to Ethernet used in PPPoE that uses comparatively massive, variable-length packets to try and do no matter what it must do.
Main Differences Between PPPoE and PPPoA
- PPPoE is more commonly used than PPPoA
- PPPoA has way more negatives than PPPoE, hence it outweighs the sole negatives in PPPoE. Hence, PPPoE ought to be the most preferred and famous to be selected by each supplier and end-users whereas As seen already, PPPoA has many more negatives than PPPoE, hence PPPoA is less popular or less preferred to use.
