Many internet users are often plagued with the decision of what kind of protocol to use with their connection. There are many questions, experimentation, and flip-flopping between PPPoE and PPPoA. Unfortunately, many of the confusions hover above these two protocols.

 

Both of these protocols give internet service providers (ISP) the capability to rollout broadband use. Using these protocols gives relative security as it obliges the end-user to verify or authenticate to a server before having network access.

PPPoE and PPPoA are mainly used with Digital Subscriber Line (DSL). Both protocols provide flexibility in billing which is very advantageous to providers. Moreover, the use of network resources can be monitored easily and along with this feature, troubleshooting and managing network usage is less problematic.

PPPoE is an abbreviation Point-to-Point Protocol over Ethernet and it is a kind of networking protocol that encapsulates PPP frames inside the Ethernet frames. Basically, PPPoE is configured as a point to point connection between two Ethernet ports.

 

Point-to-Point Protocol over ATM (PPPoA) is also a network protocol but this time, it is for encapsulating frames inside AAL5 or ATM Adaption Layer 5. ATM means Asynchronous Transfer Mode, a kind of switching using time division multiplexing in an asynchronous manner

BASIC DIFFERENCES OF PPPoE VS PPPoA are as follows:-

 

1. PPPoE means Point-to-Point Protocol over Ethernet while PPPoA means Point-to-Point Protocol over ATM.

2. PPPoE encapsulates PPP frames inside the Ethernet frames while PPPoA encapsulates frames inside AAAL5.

3. PPPoE is often used in lower packages while PPPoA is often used in enterprise packages.

4. PPPoE is more commonly used than PPPoA.

 

5. PPPoA has slightly less overhead than PPPoE therefore, it is a bit faster.

 

***Note

PROTOCOL: Sets of Rules and Regulations.

PPPoE : Point-to-Point Protocol over Ethernet.

PPPoA : Point-to-Point Protocol over ATM.

PPPoE = Point to Point Protocol over Ethernet – which is a certain way of sending packets, can't exactly remember the complexities but Ethernet packets are better for shorter distance IIRC.

PPPoA = Point to Point Protocol over ATM – Another way of sending packets, better for longer distance with less errors? IIRC
