(also The Point-to-Point Protocol over Ethernet)
A network protocol that encapsulates Point-to-Point Protocol (PPP) within the Ethernet link-layer protocol. PPPoE combines the security features of PPP and Ethernet, which supports multiple users on a LAN. PPPoE manages the data traveling over the cable networks. It also allows a single server connection to be divided between multiple clients. As a result, multiple clients can connect to the same server and access the internet simultaneously, unlike PPP, which allows only one-on-one connections. When PPPoE was first implemented, ISPs could start offering internet connection to more people.
PPPoE is considered to be outdated technology and is increasingly being replaced by DHCP. As it supports automatic IP assignment and enables IP usage monitoring and reassignment, DHCP makes network administrators’ work easier, faster, and less prone to human error.
