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.
