4.4.3 PPPoE
PPPoE provides service providers similar billing and access control as present in dial-
up services. In addition, with direct support to Ethernet it provides a low cost
solution to supporting multiple hosts at the customer premises. PPPoE provides
session authentication using Password Authentication Protocol (PAP) or Challenge
Handshake Authentication Protocol (CHAP). Session accounting is possible and
conservation of bandwidth can be done by closing down unused sessions. By utilizing
PPP, link and network parameters are easily negotiated between the IAD/Router and
the ISP.
When using PPPoE, the system is assigned an IP address from the Internet Service
Provider as part of establishing the network connection. The system can be
configured as a DHCP server for its LAN and NAT can be used to translate private
addresses to public addresses. In this way, computers in the LAN do not have to
have their own public IP addresses.
