Infrastructure Mode
A wireless network that is built around one or more access points to provide wireless clients
access to wired LAN / Internet service. The opposite of Infrastructure mode is Adhoc
mode.
IP Address
IP (Internet Protocol) is a Layer 3 network protocol that is the basis of all Internet
communication. An IP address is 32-bit number that identifies each sender or receiver of
information that is sent across the Internet. An IP address has two parts: an identifier of a
particular network on the Internet and an identifier of the particular device (which can be a
server or a workstation) within that network. The new IPv6 specification supports 128-bit IP
address format.
IPsec
IP Security. A set of protocols developed by the IETF to support secure exchange of
packets at the IP layer. IPsec has been deployed widely to implement Virtual Private
Networks (VPNs). IPsec supports two encryption modes: Transport and Tunnel.
Transport mode encrypts only the data of each packet, but leaves the header untouched.
The more secure Tunnel mode encrypts both the header and the payload. On the receiving
side, an IPSec-compliant device decrypts each packet.
LACP (802.3ad) Trunking
Link Aggregation Control Protocol. It is protocol defines how to combine the several
Ethernet ports into one high-bandwidth port to increase the transmission speed. It is also
known as port trunking. Both devices must set the trunking feature to work.
MAC
Media Access Control. MAC address provides Layer-2 identification for network devices.
Each Ethernet device has its own unique address. The first 6 digits are unique for each
device manufacturers. When a network device has MAC access control feature, only the
devices with the approved MAC address can connect with the network.
