Subnet
For routing purposes, IP networks can be divided into logical subnets by using a subnet mask. Values below
those of the mask are valid addresses on the subnet.
TCP
Transmission Control Protocol - The major transport protocol in the Internet suite of protocols provides reliable,
connection-oriented full-duplex streams.
TFTP
Trivial File Transfer Protocol - A simple file transfer protocol (a simplified version of FTP) that is often used to boot
diskless workstations and other network devices such as routers over a network (typically a LAN).
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
So named because 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 datagrams 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.
