PPPoE: (Point-to-Point Protocol over Ethernet.) Point-to-Point Protocol is a secure data
transmission method originally created for dial-up connections; PPPoE is for Ethernet
connections. PPPoE relies on two widely accepted standards, Ethernet and the Point-to-Point
Protocol. It is a communications protocol for transmitting information over Ethernet between
different manufacturers.
Protocol: A protocol is a set of rules for interaction agreed upon between multiple parties so
that when they interface with each other based on such a protocol, the interpretation of their
behavior is well defined and can be made objectively, without confusion or misunderstanding.
Router: A router is an intelligent network device that forwards packets between different
networks based on network layer address information such as IP addresses.
Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided by your
ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. It is used to
create IP address numbers used only within a particular network (as opposed to valid IP
address numbers recognized by the Internet, which must be assigned by InterNIC).
