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-

802.11standard, 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.
