PPP over Ethernet

The PPP over Ethernet Protocol, commonly known as PPPoE, is a networking protocol used to establish a point-to-point connection between two devices using Ethernet as the data link layer. PPPoE is often used by Internet Service Providers (ISPs) to provide broadband internet access to customers.

With PPPoE, a user's computer connects to the ISP's network through a DSL modem or broadband router, which acts as a PPPoE client. The PPPoE client then sends and receives data packets over the internet by encapsulating them in Ethernet frames.

This process is made possible through the use of the PPP protocol, which establishes a secure and reliable connection between the user's device and the ISP's network. PPPoE also provides authentication and encryption mechanisms to ensure that only authorized users are able to access the network.

PPPoE has become a widely used networking protocol due to its reliability and security features, making it an ideal solution for ISPs looking to provide broadband internet services to their customers.
