UDP neither guarantees delivery nor does it require a connection. It is lightweight and
efficient. All error processing and retransmission must be performed by the application
program.
Unicast
A Unicast sends a message to a single, specified receiver. In wireless networks, unicast
usually refers to an interaction in which the access point sends data traffic in the form of
IEEE 802.1x Frames directly to a single client station MAC address on the network.
Some wireless security modes distinguish between how unicast, multicast, and broadcast
frames are encrypted or whether they are encrypted.
See also Multicast and Broadcast.
URL
A Uniform Resource Locator (URL) is a standard for specifying the location of objects on the
Internet, such as a file or a newsgroup. URLs are used extensively in HTML documents to
specify the target of a hyperlink which is often another HTML document (possibly stored
on another computer). The first part of the URL indicates what protocol to use and the
second part specifies the IP address or the domain name where that resource is located.
VLAN
A virtual LAN (VLAN) is a software-based, logical grouping of devices on a network that
allow them to act as if they are connected to a single physical network, even though they
may not be. The nodes in a VLAN share resources and bandwidth, and are isolated on
that network. The Gateway 7001 Series Self-Managed AP supports the configuration of a
wireless VLAN. This technology is leveraged on the access point for the “virtual” guest
network feature.
VPN
A Virtual Private Network (VPN) is a network that uses the Internet to connect its nodes.
It uses encryption and other mechanisms to make sure that only authorized users can
access its nodes and that data cannot be intercepted.
WAN
A Wide Area Network (WAN) is a communications network that spans a relatively large
geographical area, extending over distances greater than one kilometer. A WAN is often
connected through public networks, such as the telephone system. It can also be connected
through leased lines or satellites.
The Internet is essentially a very large WAN.
WDS
A Wireless Distribution System (WDS) allows the creation of a completely wireless
infrastructure.
