INFORMATION
------------------------------------------------------------------------------------------------------------------
Proxy server
A proxy or proxy server is a service program for
computer networks that administers data trans-
fer. It makes data transfer faster, and can also
increase security by implementing access control
mechanisms.
The transfer is conducted between computers or
programs in computer networks. On the server
side, the proxy acts as a client; on the client side,
it acts as a server.
Router
A router is a network component that links sev-
eral computer networks.
The router analyses (on the basis of layer 3 in-
formation) the network packages of a protocol it
receives and forwards it to the intended destina-
tion network.
Conventional routers work on layer 3 of the
application layer. A router has an interface for
every network connected to it. When data is re-
ceived, the router determines the correct path to
the destination and thereby the suitable interface
via which the data can be transferred. For this it
uses a locally available routing table that speci-
fies via which router connection a particular net-
work can be reached.
Security (WEP/WPA)
WEP (wired equivalent privacy) is the standard
encryption algorithm for WLAN. It controls both
access to the network as well as ensuring the
confidentiality and integrity of data. This proce-
dure is considered insecure nowadays.
For this reason, more recent WLAN installations
should use the more secure WPA encryption.
V-Tuner
Service provider that provides Internet radio sta-
tions.
Wi-Fi
The Wi-Fi Alliance is an organisation that has
taken on the task of certifying products from dif-
ferent manufacturers on the basis of the IEEE-
802.11 standard, thereby ensuring that different
wireless devices can operate in parallel.
On 31 October 2002, the consortium an-
nounced a new encryption technology – Wi-Fi
Protected Access (WPA) – a part of the (then)
forthcoming IEEE standard 802.11i which
would replace the WEP encryption procedure,
which was already regarded as insecure before
the new standard came into force. After 802.11i
came into force, the Wi-Fi group coined the term
WPA2.
IEEE 802.11e is an industrial standard issued
by the Institute of Electrical and Electronics En-
gineers (IEEE) and a supplement to the wireless
LAN standard IEEE 802.11 for supporting the
quality of service.
802.11e works according to a similar principle
as the QoS procedure DiffServ. Data packages
in the WLAN are marked by the sender and the
access point is stopped in order to handle pack-
ages with higher priority.
With the aid of 802.11e, real-time application
such as Voice over IP are better supported as
they require a certain bandwidth in the network
to ensure the connection is not interrupted if
other network traffic creates too great a burden
on the available data transfer rate.
