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.
