Explanation
Service Set Identifier. A 32-character unique identifier attached to the
header of packets sent over a Wireless LAN that acts as a password
when a wireless device tries to connect to the Basic Service Set
(BSS). Several BSSs can be joined together to form one logical WLAN
segment, referred to as an extended service set (ESS). The SSID is
used to identify the ESS.
In 802.11 networks, each Access Point advertises its presence several
times per second by broadcasting beacon frames that carry the ESS
name (SSID). Stations discover APs by listening for beacons, or by
sending probe frames to search for an AP with a desired SSID. When
the station locates an appropriately-named Access Point, it sends an
associate request frame containing the desired SSID. The AP replies
with an associate response frame, also containing the SSID.
Some APs can be configured to send a zero-length broadcast SSID in
beacon frames instead of sending their actual SSID. The AP must
return its actual SSID in the probe response.
Secure Sockets Layer. A protocol developed by Netscape for
transmitting private documents via the Internet. SSL works by using a
public key to encrypt data that's transferred over the SSL connection.
URLs that require an SSL connection start with https: instead of http.
SSL uses a program layer located between the Internet's Hypertext
Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers.
The "sockets" part of the term refers to the sockets method of passing
data back and forth between a client and a server program in a
network or between program layers in the same computer. SSL uses
the public-and-private key encryption system from RSA, which also
includes the use of a digital certificate.
SSL has recently been succeeded by Transport Layer Security (TLS),
which is based on SSL.
(See netmask)
Portions of networks that share the same common address format. A
subnet in a TCP/IP network uses the same first three sets of numbers
(such as 198.63.45.xxx), leaving the fourth set to identify devices on
the subnet. A subnet can be used to increase the bandwidth on the
network by breaking the network up into segments.
SpectraLink Voice Protocol, a protocol developed by SpectraLink to be
implemented on access points in order to facilitate voice prioritization
over an 802.11 wireless LAN that will carry voice packets from
SpectraLink wireless telephones.
