Term
Definition
Layer 2
Data link layer of the Open Systems
Interconnection (OSI) model. This
corresponds to the Link layer of the
Internet protocol suite.
MAC
Address
Media Access Control Address. This is a
globally unique identifier attached to a
network adapter. It also identifies the
hardware manufacturer.
Mbps
Megabits per second. Also Mbit/s. This
is a measure of the data rate.
MiniPCIe
Mini Peripheral Component
Interconnect Express. A miniPCIe radio is
a radio card that can be inserted into a
unit's circuit board.
MTU
Maximum transmission unit. This is the
size, in bytes, of the largest packet that
can be passed on. The MTU for Ethernet
is a 1500-byte packet.
NAT
Network Address Translation. This is the
process of rewriting IP addresses as a
packet passes through a controller or
firewall. NAT enables multiple
computers (or hosts) on a LAN to access
the Internet using the single public IP
address of the LAN's gateway controller.
NMS
Network Management Station. This is a
software which runs on the SNMP
manager. It is sometimes simply referred
to as an SNMP manager.
NTP
Network Time Protocol. This is a
protocol for synchronizing a controller
to a single clock on the network, known
as the clock master.
PAP
Password Authentication Protocol. This
is a protocol for authenticating users to
a remote access server or ISP.
PPPoE
Point-to-Point Protocol over Ethernet.
This is a protocol for connecting a
Term

network of hosts to an ISP without the
ISP having to manage the allocation of IP
addresses.
PPTP
Point-to-Point Tunneling Protocol. This is
a protocol for the creation of VPNs for
the secure transfer of data from remote
clients to private servers over the
Internet.
QoS
Quality of Service. This is the
prioritization of network traffic. Voice
traffic gets the highest priority, followed
by video, best effort, and background
traffic, in this order.
RADIUS
Remote Authentication Dial In User
Service. This is a networking protocol
that provides Authentication,
Authorization, and Accounting (AAA)
management for remote users. The
RADIUS provides centralized
management of usernames and
passwords.
SNMP
Simple Network Management Protocol.
This is an Internet-standard protocol for
managing devices on IP networks. It
consists of a set of standards for
network management, including an
application layer protocol, a database
schema, and a set of data objects. SNMP
exposes management data in the form
of variables on the managed systems,
which describe the system
configuration. These variables can then
be queried (and sometimes set) by
managing applications.
SSID
Service Set Identifier. This is also known
as the ESSID or the wireless network
name.
Station
A device that connects wirelessly to an
access point.
