Glossary
MAC Address Standardized data link layer address that is required for every
port or device that connects to a LAN. Other devices in the
network use these addresses to locate specific ports in the
network and to create and update routing tables and data
structures. MAC addresses are 6bytes long and are controlled by
the IEEE.
NAT Network Address Translation: An IETF standard that allows an
organization to present itself to the Internet with far fewer IP
addresses than there are nodes on its internal network. The NAT
technology, which is typically implemented in a router, converts
private IP addresses (such as in the 192.168.0.0 range) of the
machine on the internal private network to one or more public IP
addresses for the Internet. It changes the packet headers to the
new address and keeps track of each session. When packets
come back from the Internet, NAT performs the reverse
conversion to the IP address of the client machine.

PPPoE Point-to-Point Protocol over Ethernet. PPPoE relies on two widely
accepted standards: PPP and Ethernet. PPPoE is a specification
for connecting the users on an Ethernet to the Internet through a
common broadband medium, such as a single DSL line, wireless
device or cable modem. All the users over the Ethernet share a
common connection, so the Ethernet principles supporting
multiple users in a LAN combines with the principles of PPP,
which apply to serial connections.
SNMP Simple Network Management Protocol. A network management
protocol that provides a means to monitor and control network
devices, and to manage configurations, statistics collection,
performance, and security. SNMP works by sending messages,
called protocol data units (PDUs), to different parts of a network.
SNMP-compliant devices, called agents, store data about
themselves in Management Information Bases (MIBs) and return
this data to the SNMP requesters.
SU Subscriber Unit
TCP/IP Transmission Control Protocol/Internet Protocol. A set of
protocols developed by the U.S. Department of Defense to allow
communication between dissimilar networks and systems over
long distances. TCP/IP is the de facto standard for data
transmission over networks, including the Internet.
