Telnet 
The virtual terminal protocol in the Internet suite of protocols - Allows users of one 
host to log into a remote host and act as normal terminal users of that host. 
 
Transparent bridging 
The intelligence necessary to make relaying decisions exists in the bridge itself and is 
thus transparent to the communicating workstations. It involves frame forwarding, 
learning workstation addresses, and ensuring no topology loops exist (in conjunction 
with the Spanning-Tree algorithm). 
 
UDP 
User Datagram Protocol - A connectionless transport protocol that runs on top of 
TCP/IP's IP. UDP, like TCP, uses IP for delivery; however, unlike TCP, UDP 
provides for exchange of datagram without acknowledgments or guaranteed delivery. 
Best suited for small, independent requests, such as requesting a MIB value from an 
SNMP agent, in which first setting up a connection would take more time than 
sending the data. 
 
UNI signaling 
User Network Interface signaling for ATM communications. 
 
Virtual Connection (VC) 
A link that seems and behaves like a dedicated point-to-point line or a system that 
delivers packets in sequence, as happens on an actual point-to-point network. In 
reality, the data is delivered across a network via the most appropriate route. The 
sending and receiving devices do not have to be aware of the options and the route is 
chosen only when a message is sent. There is no pre-arrangement, so each virtual 
connection exists only for the duration of that one transmission. 
 
WAN 
Wide area network - A data communications network that spans any distance and is 
usually provided by a public carrier (such as a telephone company or service 
provider).
