UDP
User Datagram Protocol
UDP is a
Protocol
of the
TCP/IP
protocol family that handles data transport between two
communication partners (applications). Unlike
TCP
, UDP is a non-session based proto-
col. It does not establish a fixed connection. The data packets, so-called datagrams, are
sent as a
Broadcast
. The recipient is responsible for making sure the data is received. The
sender is not notified about whether it is received or not.
UPnP
Universal Plug and Play
UPnP technology is used for the spontaneous linking of home or small office networks.
Devices that support UPnP carry out their network configuration automatically once
they are connected to a network. They also provide their own services or use services of
other devices in the network automatically.
URL
Universal Resource Locator
Globally unique address of a domain on the
Internet
.
VCI
Virtual Channel Identifier
Part of an address in an ATM network.
Virtual server
A virtual
Server
provides a service on the
Internet
that runs not on itself, but on another
network component. The Gigaset SE555 WLAN dsl can be configured as a virtual server.
It will then direct incoming calls for a service via
Port forwarding
directly to the appro-
priate
Port
of the network component in question.
VPI
Virtual Path Identifier
Part of an address in an ATM network.
WAN
Wide Area Network
A WAN is a network that is not restricted to one particular area, such as the
Internet
. A
WAN is run by one or more public providers to enable private access. You access the
Internet via an
Internet service provider
.
WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the
IEEE 802.11
standard. It is used to protect wire-
less transmissions in a
WLAN
against unauthorised access through
Encryption
of the
data transmitted.
