INFORMATION
Router
A router is a network component that links several computer networks.
The router analyses (on the basis of layer 3 information) the network packages of a protocol it receives and forwards it to the intended destination 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 received, the router determines the correct path to the desti- nation and thereby the suitable interface via which the data can be transferred. For this it uses a locally available routing table that spec- ifies via which router connection a particular network 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 procedure is seen as in- secure nowadays.
For this reason, more modern WLAN installations should use the more secure WPA encryption.
V-Tuner
Service provider that provides Internet radio stations.
Wi-Fi
The
802.11standard and thereby ensuring that different wireless devices can operate in parallel.
On 31 October 2002 the consortium announced a new encryption technology –
IEEE 802.11e is an industrial standard of the Institute of Electrical and Electronics Engineers (IEEE) and a supplement to the wireless LAN standard IEEE 802.11 for supporting quality of service.
802.11e works according to a similar principle to the QoS proce- dure DiffServ. Data packages in the WLAN are marked by the sender and the access point is stopped in order to handle packages with higher priority.
With the aid of 802.11e
