What is PPPoE on routers: how it works and its advantages
Most of the ISPs (Internet Service Providers) from around the world offer broadband internet subscriptions. Some of them do this through a technology called PPPoE (Point-to-Point Protocol over Ethernet). However, even if you know how to configure a PPPoE connection at home, there's still a chance 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 We 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 establish PPP connections over the Ethernet protocol. Usually used to establish a DSL Internet connection. Because a DSL modem is usually connected to a computer via an Ethernet connection, a standard PPP dial-up 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.
Point-to-Point Protocol is a network protocol that allows communication between two computers, using a serial interface. This protocol was prevalent before the 2000s when dial-up internet connections were widely used. Back then, the most common situation in which a home user would use PPP was establishing a connection between his computer and a server from a telecommunications company, using a modem and a telephone line. It's called a dial-up connection, and it's a means for people to access the internet.
However, due to the internet and technology growing rapidly over time. Several years later, using dial-up connections was no longer effective, connecting to the Internet at speeds of 28 or 56 kbit/s was unacceptable. It is also worth mentioning that the old dial-up connection using the PPP protocol could only connect one personal computer to the ISP's server. Because companies and home users wanted to connect more than one computer to the internet simultaneously, but also because of the rapid growth of the internet and the demand for higher network speeds, new network protocols 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 example of how it works:
Think of an old dial-up connection like a telephone conversation between you and your boss. Only the two of you can participate in the conversation. However, what if your boss wants to talk to your entire team? If your conversation is a dial-up connection, all of your team should huddle around the same phone earpiece. That would be an ineffective conversation, wouldn't it? The old PPP network protocol was like that, only one to one connections were 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 is speaking to your entire team, but you'll have speakers so you don't have to crowd around one tiny earpiece.
The advantages and disadvantages of PPPoE
The advantages of PPPoE are that it is easy to set up and offers important network 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 every packet that is sent. While this is only a fraction of packets that have an MTU of 1500 bytes, some connections use packets as small as 60 bytes, meaning PPPoE adds over 13% overhead. For this reason, many DSL providers now offer DHCP configuration as well.
PPPoE characteristics
* PPPoE is typically used by Internet distributors to provide connections to their subscribers.
* 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 preferred protocols that ISPs use when handling Internet connections. It also allows ISPs to manage and sell different Internet subscriptions.
* PPPoE uses a unique username and password to set speed limits, calculate, and sometimes to filter internet traffic.
Conclusion
So what is PPPoE is a network protocol sometimes used by broadband modems for DSL Internet services. PPPoE allows ISPs to manage access to accounts via a usename and password which is often configured on the DSL modem or router itself and requires no additional software configuration. Basically, PPPoE offers ISPs an easier way to track exactly how much bandwidth users are using.
