Learn To Connect PPPoE Networks

PPPoE or Point-to-Point Protocol over Ethernet, is a specification that enables multiple users on an Ethernet LAN (local area network) to connect to various devices. It is often used in offices where users share a single DSL (Digital Subscriber Line), a cable model or a wireless connection to the web. PPPoE is a combination of Point-to-Point Protocol, a method mostly used for dial-up connections, and Ethernet Protocol, a method commonly used by multiple users in a LAN. It functions by encapsulating the PPP data into the Ethernet frame. PPPoE has an advantage that cannot be provided by neither an ISP or telephone company. In contrast to dial-up connections, DSL and cable modems are always connected to the internet. Being that a large number of users may need to share the same connection to a remote service provider, there needs to be a way to track how traffic is directed and which users should be billed. PPPoE is the protocol that enables the sessions from a remote-user site to determine each other’s network address. After a session has been established between the remote site and an individual user, it can then be monitored for billing accuracy. Several apartment complexes, corporations and hotels are currently providing shared internet access over DSL lines using PPPoE.
