UPnP Universal Plug and Play. The goals of UPnP are to allow
devices to connect seamlessly and to simplify the
implementation of networks in the home (data sharing,
communications, and entertainment) and in corporate
environments for simplified installation of computer
components
User Priority User Priority is a 3-bit field that stores the priority level for the
802.1Q frame.
V
VLAN
Virtual LAN. A method to restrict communication between
switch ports. VLANs can be used for the following applications:
VLAN unaware switching
: This is the default configuration.
All ports are VLAN unaware with Port VLAN ID 1 and members
of VLAN 1. This means that MAC addresses are learned in
VLAN 1, and the switch does not remove or insert VLAN tags.
VLAN aware switching
: This is based on the IEEE 802.1Q
standard. All ports are VLAN aware. Ports connected to VLAN
aware switches are members of multiple VLANs and transmit
tagged frames. Other ports are members of one VLAN, set up
with this Port VLAN ID, and transmit untagged frames.
Provider switching
: This is also known as Q-in-Q switching.
Ports connected to subscribers are VLAN unaware, members
of one VLAN, and set up with this unique Port VLAN ID. Ports
connected to the service provider are VLAN aware, members
of multiple VLANs, and set up to tag all frames. Untagged
frames received on a subscriber port are forwarded to the
provider port with a single VLAN tag. Tagged frames received
on a subscriber port are forwarded to the provider port with a
double VLAN tag.
VLAN ID VLAN ID is a 12-bit field specifying the VLAN to which the
frame belongs.
Voice VLAN Voice VLAN is VLAN configured specially for voice traffic. By
adding the ports with voice devices attached to voice VLAN,
QoS-related configuration for voice data can be performed,
ensuring the transmission priority of voice traffic and voice
quality.
W
WEP
Wired Equivalent Privacy. WEP is a deprecated algorithm to
secure IEEE 802.11 wireless networks. Wireless networks
broadcast messages using radio, so are more susceptible to
eavesdropping than wired networks. When introduced, WEP
was intended to provide data confidentiality comparable to that
of a traditional wired network (Wikipedia).
Wi-Fi Wireless Fidelity. It is meant to be used generically when
referring of any type of 802.11 network, whether 802.11b,
802.11a, dual-band, etc. The term is promulgated by the Wi-Fi
Alliance.
