PPPoE
Point-to-Point Protocol over
Ethernet
PPPoE is a
Protocol
for connecting network components in a local Ethernet network to
the
Internet
via a modem.
PPTP
Point-to-Point
Tunneling
Protocol
An
Internet
connection using PPTP
Protocol
that creates a "tunnel" within an Internet
connection for a secure private connection in which the data are sent in encrypted form.
The PPTP protocol is used in a Virtual Private Network (VPN).
Private IP address
The private
IP address
is a network component's address within the local area network
(LAN). The network operator can assign any address he or she wants. Devices that act
as a link from a local network such as the Gigaset SE505 dsl/cable have a private and a
Public IP
address.
Protocol
A protocol describes the agreements for communication on a network. It contains rules
for opening, administering and closing a connection, about data formats, time frames
and error handling. Communications between two applications require different proto-
cols at various levels, e.g. the
TCP/IP
protocols for the Internet.
Public IP address
The public
IP address
is a network component's address on the Internet. It is assigned by
the
Internet Service
Provider. Devices that create a link from a LAN to the Internet, such
as the Gigaset SE505 dsl/cable, have a public and a
Private IP
address.
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 area network (LAN).
Repeater
A repeater extends the range of a wireless local area network by relaying data from the
Access point
to additional PCs or
Network
adapter.
Roaming
In order to extend the range of a wireless local network, roaming involves several
Access
points
or Repeaters which use the same
SSID
and radio channel and are connected via
Ethernet. The PC's within the network can switch dynamically between several Access
Points without losing an existing network connection.
Router
A router directs data packets from one local area network (LAN) to another via the fast-
est route. A router makes it possible to connect networks that have different network
technologies. For example, it can link a local network with
Ethernet
or
WLAN
technol-
ogy to the Internet.
