address can connect with the network.
TCP
A layre-4 protocol used along with the IP to send data between computers over the Internet. While IP
takes care of handling the actual delivery of the data, TCP takes care of keeping track of the packets
that a message is divided into for efficient routing through the Internet.
UDP
User Datagram Protocol. A layer-4 network protocol for transmitting data that does not require
acknowledgement from the recipient of the data.
QoS (Bandwidth Management)
Bandwidth Management controls the transmission speed of a port, user, IP address, and application.
Router can use bandwidth control to limit the Internet connection speed of individual IP or Application.
It can also guarantee the speed of certain special application or privileged IP address - a crucial feature
of QoS (Quality of Service) function. For switch's bandwidth management, please see "Rate Control".
RADIUS
Remote Authentication Dial-In User Service. An authentication and accounting system used by many
Internet Service Providers (ISPs). When you dial in to the ISP, you must enter your username and
password. This information is passed to a RADIUS server, which checks that the information is correct,
and then authorizes access to the ISP system. RADIUS typically uses port 1812 and port 1813 for
authentication and accounting port. Though not an official standard, the RADIUS specification is
maintained by a working group of the IETF.
Wake on Lan
Wake on Lan (WOL) function works to power on the computer remotely. The computer’s network card
must also support WOL function, when it receive the waked up packets and the computer will auto boot
up.
VPN
Virtual Private Network. A type of technology designed to increase the security of information over the
Internet. VPN creates a private encrypted tunnel from the end user’s computer, through the local
wireless network, through the Internet, all the way to the corporate network.
IPsec
IP Security. A set of protocols developed by the IETF to support secure exchange of packets at the IP
layer. IPsec has been deployed widely to implement Virtual Private Networks (VPNs). IPsec
