Network protocol
The network protocol is the standard via which different PCs exchange data in a net-
work. A connection can only be established between PCs in a network if they all use
the same protocol. The
col, which is also used for connections to the Internet. This must be set up on each PC
from which a network connection is to be established.
Port
Data is exchanged between two applications in a network across a port. The port num-
ber addresses an application within a network component. The combination of
address/port number uniquely identifies the recipient or sender of a data packet within
a network. Some applications (e.g. Internet services such as HTTP or FTP) work with
fixed port numbers; others are allocated a free port number whenever they need one.
Port forwarding
In port forwarding, the Cisco BWX360 WiMAX Outdoor Modem directs data packets
from the Internet that are addressed to a particular
appropriate network component. This enables servers within the local network to offer
services on the Internet without them needing a public IP address. See also:

Protocol
A protocol describes the agreements for communicating on a network. It contains rules
for opening, administering and closing a connection, as well as about data formats,
time frames and handling possible errors. Communications between two applications
require different protocols at various levels, e.g. the
Provider
A provider (Internet Service Provider) offers access to the Internet for a fee.
RJ
Registered Jack. Standardised connection, also known as a modular jack.
Router
A router directs data packets from one local area network (LAN) to another via the fast-
est route. A router enables the connection between networks of different network tech-
nologies and this is performed on the basis of a common protocol. For example, it can
link a local network with WiMAX technology to the Internet.
RSSI
Received Signal Strength Indication. Characteristic value for the signal strength of
radio connections, used by communication devices for the automatic selection of a suit-
able channel.
