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 communication 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).
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable Datagram
Protocol (UDP). TCP/IP is the standard protocol for data transmission over the Internet. Both TCP and
UDP are transport layer protocols. TCP performs proper error detection and error recovery, and thus is
reliable. UDP on the other hand is not reliable. They both run on top of the IP (Internet Protocol), a
network layer protocol.
WAN: Wide Area Network. A network that connects computers located in geographically separate areas
(e.g. different buildings, cities, countries). The Internet is a wide area network.
Web-based management Graphical User Interface (GUI): Many devices support a graphical user
interface that is based on the web browser. This means the user can use the familiar Netscape or Microsoft
Internet Explorer to Control/configure or monitor the device being managed.
3G telecommunication networks: Supports services that provide an information transfer rate of at least
200 kbit/s. However, many services advertised as 3G provide higher speed than the minimum technical
requirements for a 3G service. Later 3G releases, often denoted 3.5G and 3.75G, also provide mobile
broadband access of several Mbit/s to smartphones and mobile modems in laptop computers.
