TLV
TLV is an acronym for Type Length Value. A LLDP frame can contain multiple pieces of information.
Each of these pieces of information is known as TLV.
TKIP
TKIP is an acronym for Temporal Key Integrity Protocol. It used in WPA to replace WEP with a new
encryption algorithm. TKIP comprises the same encryption engine and RC4 algorithm defined for
WEP. The key used for encryption in TKIP is 128 bits and changes the key used for each packet.
U
UDP
UDP is an acronym for User Datagram Protocol. It is a communications protocol that uses the Internet
Protocol (IP) to exchange the messages between computers.
UDP is an alternative to the Transmission Control Protocol (TCP) that uses the Internet Protocol (IP).
Unlike TCP, UDP does not provide the service of dividing a message into packet datagrams, and UDP
does not provide reassembling and sequencing of the packets. This means that the application
program that uses UDP must be able to make sure that the entire message has arrived and is in the
right order. Network applications that want to save processing time because they have very small
data units to exchange may prefer UDP to TCP.
UDP provides two services not provided by the IP layer. It provides port numbers to help distinguish
different user requests and, optionally, a checksum capability to verify that the data arrived intact.
Common network applications that use UDP include the Domain Name System (DNS), streaming
media applications such as IPTV, Voice over IP (VoIP), and Trivial File Transfer Protocol (TFTP).
UPnP
UPnP is an acronym for 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 storing the priority level for the 802.1Q frame. It is also known as PCP.
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.
