What is PPPoE on a router: how it works and its advantages


What is PPPoE


Most of the ISPs (Internet Service Providers) from around the world offer broadband internet subscriptions. Some of them do so through a technology called PPPoE (Point-to-Point Protocol over Ethernet). However, even if you know how to configure a PPPoE connection at home, it is still possible. It's possible that you don't know what PPPoE means or how PPPoE works. If you want to understand what PPPoE is, then you should read this article. Here the admin will explain this concept as clearly as possible. Let's get started.

What is PPPoE?


PPOE stands for "Point-to-Point Protocol over Ethernet." PPPoE is a network configuration used to make PPP connections over the Ethernet protocol. Usually used to make DSL Internet connections. Because DSL modems are usually connected to computers over an Ethernet connection, a standard dial-up PPP connection cannot be used. Therefore, PPP over Ethernet allows a computer to connect to an internet service provider (ISP) via a DSL modem.


PPPoE History


According to Wikipedia, PPPoE was developed by UUNET, Redback Networks (now Ericsson) and RouterWare (now Wind River Systems) in the 2000s, and became popular a few years later.


The Point-to-Point Protocol is a network protocol that allows communication between two computers, using a serial interface. This protocol was commonly used before the 2000s when dial-up Internet connections were widely used. At that time, the most common situation where users A homeowner will use PPP is to establish a connection between his computer and a server from a telecommunications company, using a modem and a telephone line. This is called a dial-up connection, and it is a means for people to access the internet.


However, as the internet and technology grew rapidly over time. A few years later, using a dial-up connection was no longer effective, connecting to the Internet at a speed of 28 or 56 kbit/s was unacceptable. It should also be mentioned that a connection Old dial-up using the PPP protocol can only connect one personal computer to the ISP server. Because companies and home users want to connect more than one computer to the internet at the same time, but also because of the fast growth of the internet and the demand for higher network speeds. , a new network protocol had to be developed. That's when PPPoE came out.

How PPPoE Works


PPPoE is usually used by ISPs to offer internet connection to their customers. To help you understand how they use PPPoE, here is a real-life example of how it works:


Think of an old dial-up connection as a telephone conversation between you and your boss. Only the two of you can participate in the conversation. But what if your boss wants to talk to all of your team? If your conversation is a dial-up connection , all your teams have to gather around the same telephone earpiece. That would be an ineffective conversation, wouldn't it? The old PPP network protocol was like that, only one to one connection was possible.


PPPoE changes that, and it allows more client devices to use the same network to connect to a single server. It's like your boss talking to all of your team, but you'll have loudspeakers so you don't have to huddle around one tiny earpiece. .


PPPoE Advantages And Disadvantages


The advantage of PPPoE is that it is easy to set up and offers important networking features, such as authentication, data encryption, and data compression. It also supports multiple computers on a Local Area Network (LAN).


The drawback of PPPoE is that it requires additional overhead, or additional data, to be sent over the Internet connection. A standard PPPoE connection adds 8 bytes of data to each packet sent. Although this is only a fraction of the packets that have an MTU of 1500 bytes, some connections use packets as small as 60 bytes, which means PPPoE adds over 13% overhead. For this reason, many DSL providers now offer DHCP configurations as well.


PPPoE Characteristics


  * PPPoE is typically used by Internet distributors to provide connections to their customers.

  * PPPoE allows multiple clients to connect to a single server using the same network.

  * PPPoE is a network protocol that offers other basic network options such as authentication, encryption, and data compression. Because of this, PPPoE is one of the protocols of choice that ISPs use when handling Internet connections. It also allows ISPs to set up and sell different Internet subscriptions.Â

  * PPoE uses a unique username and password to set speed limits, calculate and sometimes filter internet traffic.


Conclusion


So what is PPPoE is a network protocol sometimes used by broadband modems for DSL Internet service. PPPoE allows ISPs to manage access to accounts via usernames and passwords that are often configured on the DSL modem or router itself and require no additional software configuration. Basically, PPPoE offers ISPs an easier way to track exactly how much bandwidth a user is using.
