Glossary
Tunneled Transport Layer Security (TTLS)
A proposed wireless security protocol, developed by Funk Software and Certicom, that combines
network-based certificates with other authentication such as tokens or passwords. Also known as
EAP-TTLS.
User Datagram Protocol (UDP)
provides a datagram mode for packet-switched communications. It uses IP as the underlying
UDP
transport mechanism to provide access to IP-like services. UDP packets are delivered just like IP
packets – connection-less datagrams that may be discarded before reaching their targets. UDP is
useful when TCP would be too complex, too slow, or just unnecessary.
Virtual LAN (VLAN)
A Virtual LAN is a collection of network nodes that share the same collision domain regardless of
their physical location or connection point in the network. A VLAN serves as a logical workgroup
with no physical barriers, and allows users to share information and resources as though located on
the same LAN.
XModem
A protocol used to transfer files between devices. Data is grouped in 128-byte blocks and error-
corrected.
