TCP/IP
abbreviation for Transmission Control Protocol / Internet
Protocol
TCP/IP is the “language” of the Internet. TCP/IP is used to
refer to a suite of protocols used for data communication
over the Internet. TCP and IP are the network and transport
protocols underlying most Internet services, including file
transfer (FTP) and e-mail communication (SMTP). TCP/IP is
available for practically all computer systems. TCP/IP thus
offers the advantage of trouble-free communication be-
tween otherwise incompatible networks and systems.
TR-069
T-069 is an HTTP-based protocol for communication be-
tween CPE (Customer Premises Equipment) and an Auto
Configuration Server (ACS) belonging to the Internet Ser-
vice Provider. The TR-069 protocol is also known under the
alternative name CPE WAN Management Protocol (CWMP).
It offers the possibility of setting up the terminal device
Example 2
IP address:
192.168.178.247
Subnet mask:
255.255.0.0
The assignment of the first two groups of numerals in the sub-
net mask indicates that the first two groups of numerals in the
IP address define the network. The following addresses result:
Network address of the subnet: 192.168.0.0
Address of the computer in the
subnet:
192.168.178.247
IP address pool in the subnet:
192.168.0.0 -
192.168.255.255
That’s 65,536 IP addresses.
The IP addresses 192.168.0.0
and 192.168.255.255 are re-
served. This means that the
addresses from 192.168.0.1 to
192.168.255.254 are availa-
ble for assignment to the com-
puters.
