supplicant, an authenticator, and an authentication server. The supplicant
is a client device (such as a laptop) that wishes to attach to the
LAN/WLAN - though the term 'supplicant' is also used interchangeably to
refer to the software running on the client that provides credentials to the
authenticator. The authenticator is a network device, such as an Ethernet
switch or wireless access point; and the authentication server is typically
a host running software supporting the RADIUS and EAP protocols. The
authenticator acts like a security guard to a protected network. The
supplicant (i.e. client device) is not allowed access through the
authenticator to the protected side of the network until the supplicant's
identity has been validated and authorized. With 802.1X port-based
authentication, the supplicant provides credentials, such as user name /
password or digital certificate, to the authenticator, and the authenticator
forwards the credentials to the authentication server for verification. If
the authentication server determines the credentials are valid, the
supplicant (client device) is allowed to access resources located on the
protected side of the network.
PPPOE
he Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol
T
for encapsulating PPP frames inside Ethernet frames. Integrated PPP
protocol implements authentication, encryption, and compression
functions that traditional Ethernet cannot provide and can also be used
in the cable modem and digital subscriber line (DSL) and Ethernet that
provide access service to the users. Essentially, it is a protocol that
allows to establish a point-to-point tunnel between two Ethernet
interfaces within an Ethernet broadcast domain.
DNS
The Domain Name System (DNS) is a hierarchical distributed naming
system for computers, services, or any resource connected to the
Internet or a private network. It associates various information with
domain names assigned to each of the participating entities. A Domain
Name Service resolves queries for these names into IP addresses for the
purpose of locating computer services and devices worldwide. An
often-used analogy to explain the Domain Name System is that it serves
as the phone book for the Internet by translating human-friendly
computer hostnames into IP addresses.
