The virtual connection point through which a computer uses a specific application on a 
server. 
 
 
PPPoE 
Point-to- Point Protocol over Ethernet. PPPoE relies on two widely accepted standards: 
PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the 
Internet through a common broadband medium, such as a single DSL line, wireless device 
or cable modem. 
 
 
PPTP 
Point-to-Point Tunneling Protocol: A VPN protocol developed by PPTP Forum. With 
PPTP, users can dial in to their corporate network via the Internet. If users require data 
encryption when using the Windows PPTP client, the remote VPN server must support 
MPPE (Microsoft Point-To-Point Encryption Protocol) encryption. PPTP is also used by 
some ISP for user authentication, particularly when pairing with legacy Alcatel / Thomson 
ADSL modem. 
 
 
Preamble Type 
Preamble are sent with each wireless packet transmit for transmission status. Use the 
long preamble type for better compatibility. Use the short preamble type for better 
performance 
 
 
Rate Control 
Ethernet switches' function to control the upstream and downstream speed of an individual 
port. Rate Control management uses "Flow Control" to limit the speed of a port. 
Therefore, the Ethernet adapter must also have the flow control enabled. One way to 
force the adapter's flow control on is to set a port to half-duplex mode. 
 
 
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.
