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
The 802.3ad Link Aggregation standard 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
device must set the trunking feature to work.
MAC (Media Access Control)
MAC address provides layer-2 identification for Networking Devices. Each Ethernet device has its
own unique address. The first 6 digits are unique for each manufacturer. When a network device
have MAC access control feature, only the devices with the approved MAC address can connect with
the network.
Mbps (Megabits per Second)
One million bits per second; a unit of measurement for data transmission
MESH
Mesh is an outdoor wireless technology that uses Spanning Tree Protocol (STP) and Wireless
Distribution system to achieve self-forming, self-healing, and self-configuring outdoor network. MESH
network are able to take the shortest path to a destination that does not have to be in the line of site.
MIMO (Multi-Input-Multi-Output)
A Smart Antenna technology designed to increase the coverage and performance of a WLAN
network. In a MIMO device, 2 or more antennas are used to increase the receiver sensitivity and to
focus available power at intended Rx.
