Specifications

Glossary 923
Router*
A device that forwards data packets from one local area network (LAN) or
wide area network (WAN) to another. Based on routing tables and routing
protocols, routers can read the network address in each transmitted frame
and make a decision on how to send it via the most efficient route based on
traffic load, line costs, speed, bad connections, etc.
Server*
A computer that provides its resources to other computers and devices on a
network. These include print servers, Internet servers and data servers. A
server can also be combined with a hub or router.
Site survey*
The process whereby a wireless network installer inspects a location prior to
putting in a wireless network. Site surveys are used to identify the radio- and
client-use properties of a facility so that access points can be optimally
placed.
SSH
Secure SHell, also known as secure socket shell. A UNIX-based command
interface used to gain secure access to a computer or computer network.
Alcatel implements OpenSSH.
NOTE—It is Alcatel’s policy in supporting OpenSSH to continuously apply security
patches and bug fixes. However, Alcatel does not update the OpenSSH version
string when security patches do not update the version. Changing the version
introduces possible incompatibilities with SSH client v3.2.0b267 and 4.1.3.2.
SSID*
A 32-character unique identifier attached to the header of packets sent over a
Wireless LAN that acts as a password when a mobile device tries to connect
to the BSS. (Also called ESSID.) The SSID differentiates one Wireless LAN
from another, so all access points and all devices attempting to connect to a
specific Wireless LAN must use the same SSID. A device will not be permitted
to join the BSS unless it can provide the unique SSID. Because an SSID can be
sniffed in plain text from a packet, it does not supply any security to the
network. An SSID is also referred to as a Network Name because essentially it
is a name that identifies a wireless network.
