ARP : Address Resolution Protocol is a protocol for mapping an Internet Protocol address
(IP address) to a physical computer address that is recognized in the local network.
DHCP : Dynamic Host Configuration Protocol automatically assigns IP addresses to
clients when they log on. DHCP centralizes IP address management on central
computers that run the DHCP server program. DHCP leases addresses, for a period of
time, which means that past addresses are “recycled” and made available for future
reassignment to other systems.
EAPoL : EAP (Extensible Authentication Protocol, RFC 2486) over LAN. EAP is used
with IEEE 802.1x to allow additional authentication methods (besides RADIUS) to be
deployed with no changes to the access point or the wireless clients.
PPPoE : (Point-to-Point Protocol over Ethernet) relies on 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.
NETBIOS : (Network Basic Input/Output System) are TCP or UDP broadcast packets that
enable a computer to connect to and communicate with a LAN.
IGMP : Internet Group Multicast Protocol is used when sending packets to a specific
group of hosts.
