Glossary
Protocol
A protocol describes the agreements for communicating in a network. It contains rules
for opening, administering and closing a connection, as well as in relation to data for-
mats, time frames and possibly troubleshooting. Communication between two applica-
tions requires different protocols at various levels, for example the TCP/IP protocols for
the Internet.
PVC
Permanent Virtual Circuit
A permanent virtual circuit is a logical connection in an ATM network.
QoS
Quality of Service
QoS allows network traffic to be sorted according to priorities. When this parameter is
activated, Internet telephony is given priority over other data traffic. This is a precondi-
tion for problem-free calls.
Radio network
See WLAN
Rekey interval
The rekey interval is the period after which new keys are automatically generated for
data encryption with WPA-PSK.
Remote management
Remote management refers to the ability to manage a network from a network compo-
nent that is actually outside the local network (LAN).
Repeater
A repeater extends the range of a wireless local network by relaying data from the
Access point to additional PCs or Network adapters.
Roaming
Roaming extends the range of a wireless LAN by using several Access points that use the
same SSID and the same radio channel and are linked via Ethernet. The PCs in the net-
work can switch dynamically between several access points without losing the existing
network connection.
Router
A router directs data packets from one local network (LAN) to another via the fastest
route. A router makes it possible to connect networks that have different network tech-
nologies. For example, it can link a local network with Ethernet or WLAN technology to
the Internet.
