Internet Protocol over Ethernet (IPoE) is a method of delivering an IP payload over an Ethernet-based access network or an access network using bridged Ethernet over Asynchronous Transfer Mode (ATM) without using PPPoE. It directly encapsulates the IP datagrams in Ethernet frames, using the standard encapsulation. The use of IPoE addresses the disadvantage that PPP is unsuited for multicast delivery to multiple users. Typically, IPoE uses Dynamic Host Configuration Protocol and Extensible Authentication Protocol to provide the same functionality as PPPoE, but in a less robust manner. References Link protocols
