accessed by multiple users, such as Server PCs, or printers. If you are using your Router to
share your cable or DSL Internet connection, contact your ISP to see if they have assigned
your home a static IP address. You will need that address during your Router's configuration.
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.
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).
